QGIS » QGIS Application

Ok, Thanks for feedback.
I test that method monday (office computer) and post results here.
How can i obtain more information from qgis to help you to diagnose problem?
It seem's that there is no verbose mode on qgis precompiled (repository).
Regards.

My first guess would be to start qgis without plugins enabled, or rename your .qgis2 temporarily.

I cannot reproduce here (but I'm on Buster/self compiled 2.18 here).

Information you provided here is not enough to draw conclusions about your situation.

Hello,
I've tested to remove the .qgis2 directory (in my home) --> No changes.
I've tested to install qgis at my home computer (same Debian version) --> qgis works normally.
I'm perplex.

How can I obtain logs error from qgis, or more informations, to identify problem?
You can read the std ouput in terminal:

qgis
Warning: Object::connect: No such signal QgsMergedBookmarksTableModel::&QgsMergedBookmarksTableModel::selectItem( const QModelIndex &index )
Warning: Object::connect:  (receiver name: 'QgsBookmarksBase')
Warning: QCss::Parser - Failed to load file  "/style.qss" 
QInotifyFileSystemWatcherEngine::addPaths: inotify_add_watch failed: Aucun fichier ou dossier de ce type
Warning: QFileSystemWatcher: failed to add paths: /home/euziere/.qgis2//project_templates
Warning: QLayout: Attempting to add QLayout "" to QgsPanelWidgetStack "mWidgetStack", which already has a layout
Erreur de segmentation

"Erreur de segmentation" translation is "segfault error".

Best regards.

Another file which is actually writen bij Qt4 and remembers the position and sizes of your windows is:
.config/QGIS/QGIS2.conf

Maybe try to remove that too? It could have been corrupted maybe?

Well done!
I'll realize that the QFileSystemWatcher path seems not correct.
It will be: /home/MathieuDenat/.qgis2/blablabla

I test to remove .config/QGIS/QGIS2.conf (next week) and come back to you.

Another idea: wich package reconfiguring to reset the qgis configuration?
I've do préviously:

aptitude purge qgis && aptitude install qgis

Thanks a lot and have nice day.

I asked around, and I do not think apt or aptitude should clean up these files from all home directories on a multi-user Linux system?

So my anwer would be:

rm -rf ~/.config/QGIS/QGIS2.conf
rm -rf ~/.qgis2

please close this issue if possible

Hi,
I tried to remove directories from all home diretories on all users of system (2 users + root). I launch qgis again and obtain the same error type (segfault error):

Warning: Object::connect: No such signal QgsMergedBookmarksTableModel::&QgsMergedBookmarksTableModel::selectItem( const QModelIndex &index )
Warning: Object::connect:  (receiver name: 'QgsBookmarksBase')
Warning: QCss::Parser - Failed to load file  "/style.qss" 
QInotifyFileSystemWatcherEngine::addPaths: inotify_add_watch failed: Aucun fichier ou dossier de ce type
Warning: QFileSystemWatcher: failed to add paths: /home/MathieuDenat/.qgis2//project_templates
Warning: QLayout: Attempting to add QLayout "" to QgsPanelWidgetStack "mWidgetStack", which already has a layout
Erreur de segmentation

This line could be the origin of problem or not?
QInotifyFileSystemWatcherEngine::addPaths: inotify_add_watch failed: Aucun fichier ou dossier de ce type. (error translation: file not found)

My bug look like #14781

What can I do?

Hi,

You can close de ticket. I make 2 tests:

Test 1:
I've reinstalled Debian from scratch.
Compile GDAL (with ECW support) and install qgis 3 from official repositories.

Test 2:
I test installation of Qgis3.0 on other Debian machine, and all was correct.

So, I don't konw the problem's source, but it's solved.

Thanks at lot for time.
