Is that part of the error message?

<class 'qgis.core.QgsVectorLayer'>

did you try without non-core plugins?

Yes, same result when started --noplugins

not reproducable here - please include a backtrace of the segfault.

Not reproducible here either.

Btw. there is no NULL in any feature's "value" field in provided data

I get the crash under Ubuntu/qgis-master

gio@sibirica:~$ qgis --noplugins

Backtrace please.

No crashes here, but the terminal displays the following error message:

ERROR 1: SQL Expression Parsing Error: syntax error

It seems to me the output of a GDAL error, maybe the crash depends on the GDAL version.

I'm on Ubuntu 11.04, QGis master, GDAL 1.8

also looks suspicious. Does that message appear right before the crash or earlier?

This copy of QGIS writes debugging output.

It may well be a compilation problem - now compiling and testing.

Nope, recompiled, same crash. Must be a local issue.

I also get the crash on ubuntu using the nightly build repo so it is not a local problem and if does not affects 1.7.4 it is a regression

<class 'qgis.core.QgsVectorLayer'> appears at the end of QGIS loading (only when plugins are on).

Would anyone who can actually produce the crash please also create a backtrace.

I just updated master on ubuntu and I have still the crash. I tested also to change all the values of the "label" column except one, and I still have the crash. On Windows is works ok. This is how the "about" looks like for me

I would not consider this as "normal", at least until further investigations.

The backtrace suggests that it might be a GDAL/OGR bug. Would you mind to try QGIS with a different version of GDAL? ... although some others running 1.9.0 seem not to be affected

Which GDAL 1.9 package were you using?
