Description
When Qgis starts, it crashes whith this message:
rewrewqr@ewrqwerqw:~/.config/QuantumGIS> qgis
Python support ENABLED :-)
Loaded : fTools (package: fTools)
Warning: QHttp: empty path requested is invalid -- using '/'
Loaded : Plugin Installer (package: plugin_installer)
Violación de segmento (Segmentation fault)
I've been looking around and I've found that the problem itself occurs when plugin_installer is loaded (maybe that's why if you run qgis as root it works until you try to use the plugin installer, because I guess different users have different QGIS.conf files and in root maybe the plugin is not activated by default, so it's not loaded at start)
If you modify your QGIS.conf and set the string under [PythonPlugins] plugin_installer to false, it starts (but at soon as you select the plugin in the plugin manager and accept it crashes). Also is posible to start if you set the string under [QGis] plugin-installer\\checkOnStart to false, in this case even if you have selected the plugin Qgis will start.
I don't know much about debugging and stuff but I've make a dbg qgis with this result (I ommit a lot of lines before):

Which SIP do you have?
Well, I have installed python-sip 4.9.1-1.1.1.
By the way, yesterday I've done a DIY debbugging (adding print sentences before and after loops and if-elses, etc) and I think the segfault occurs (at least) when the plugin isntaller scripts goes into line #153 in file installer_plugin.py, when calling self.fetchDlg.exec_().
Moreover, I think I've sent an useless trace made with strace, maybe is more interesting the bt from gdb. Please tell me if all this is useless or junk for future reports.
Thank you very much for your help
Cheers,
Jorge Tornero

I think the question from pcav, is does this problem still exist if you recompile QGIS from the latest trunk?

I'm so sorry I haven't answered yet, among other things a new little human being has come and qgis stuff has been left apart for a while. Thank you for your patience, I absolutely forgot about this and I have remembered when I received your message this morning.
I have to say that the problem occurs in at least three machines with opensuse 11.2, and I haven't been able to compile the sources (as I said, I am not a very, very advanced user). I did the DIY debugging and I have been sniffing around in the sources of plugin manager but no results. I also have tried to upgrade my qt libraries and all but no success.
By the way, I've realized that maybe is better to assign component property of this ticket to "Python plugins and bindings"
If you think it is worth, please tell me what I have to do (roughly) to give you the appropiate feedback on all this.
Thank you very much for your attention and, once again, my apologies.

Had a similar issue on opensuse. It appeared to be due to incompatibility with Qt, and was solved by upgrading to KDE 4.4. For a while, I was able to get by downgrading Qt, but this left a number of other apps (e.g. Digikam) not working.

Do you have any (possibly postgres related) third party plugins installed? If so, please check if the problem also appears without them and if it doesn't try to figure out which plugin is causing this.

Hello, I've installed [[PostgreSQL]] plus standard server 8.4 from enterpriseDB repository instead of the one provided by openSUSE mostly because it really works fine from zero. I'll try to check in a computer without this distribution and also with standard postgresql installation if the bug occurs as well. Best regards Jorge Tornero

He has the same [[OpenSuse]] as me, but instead of having installed [[PostgreSQL]] from [[EnterpriseDB]], he installed the packages provided by openSuse through [[YaST]] (say so, an 'standard' installation)... and it worked perfectliy, so I realized that the problem could be where Jef pointed. Because of my lack of deep knowledge about linux internals, I've done a 'brute force approach' to try to solve the problem, and... It worked!!!! I've done the following 1) First I've located all the libcrypto related files: <pre> /opt/lampp/lib/libcrypto.so /opt/lampp/lib/libcrypto.so.0.9.8 /opt/lampp/lib/pkgconfig/libcrypto.pc /opt/PostgreSQL/8.4/lib/libcrypto.so.4 /opt/PostgreSQL/psqlODBC/lib/libcrypto.so.4 /usr/lib/libcrypto.a /usr/lib/libcrypto.so /usr/lib/libcrypto.so.0.9.7 /usr/lib/libcrypto.so.0.9.8 /usr/lib/libcryptopp.a /usr/lib/pkgconfig/libcrypto.pc </pre> 2) Then I've moved away (to a subfolder in /opt/PostgreSQL/8.4/lib/libcrypto.so.4) the file libcrypto.so.4 for safety reasons 3) then I've created a symlink to /usr/lib/libcrypto.so in /opt/PostgreSQL/8.4/lib/ with the name libcrypto.so.4 And voilà, QGis works again. So I have to apologize for thinking that thas was a bug in QGis, and I have to appreciate all the help received from you. I hope that someone of you could explain what I did for future reference, and also, please tell if the bug could be marked as solved, I don't know if what I've done is enough. Thank you very much again jorge Tornero

It's probably better to use PostgreSQL with the libraries it was built with.
But you should take care that the PostgreSQL install doesn't interfere with the
rest of the system.
Your PostgreSQL install probably "infected" the system by adding a path to
Therefore libraries are also looked up in the [[PostgreSQL]] directory although the libraries there are incompatible with the rest of the system. Removing pathes should also cure the problem. But you might find that [[PostgreSQL]] doesn't work anymore. In that case you can probably setj those pathes in LD_LIBRARY_PATH in [[PostgreSQL]] startup script, so that only [[PostgreSQL]] uses it's own versions of libraries. > I hope that someone of you could explain what I did for future reference, and > also, please tell if the bug could be marked as solved, I don't know if what > I've done is enough. Sure thing. I'll close the bug. > Thank you very much again You're welcome.
