History
#1 Updated by Mathieu Pellerin - nIRV about 9 years ago
Note: as the debug details indicate, the crash has to do with gdal trying to open PDFs. None of the PDFs I have in my home folder are georeferenced. If I remove all PDFs from my home folder, the crasher is gone.
#2 Updated by Radim Blazek about 9 years ago
Poppler library was not thread safe, it should be fixed, see https://bugs.freedesktop.org/show_bug.cgi?id=50992.
Can you verify if your version of poppler lib is a fixed and thread safe?
#3 Updated by Mathieu Pellerin - nIRV about 9 years ago
I'm running on Ubuntu Wily, and the libpoppler52 version is 0.33.0-0ubuntu3. Looking at the bug, the fix was merged back in 2013, I'd expect the package in ubuntu circa 2015 to include that fix.
Weird.
#4 Updated by Radim Blazek about 9 years ago
The problems with GDAL/OGR thread safety may appear with various drivers. We should probably add mutex lock to QgsGdalLayerItem and QgsOgrLayerItem.

- Status changed from Open to Closed
This is not a problem of thread-safety, but Ubuntu having picked up only one of 2 patches to have support for Poppler >= 0.31.0 in the GDAL 1.11.X series. See https://trac.osgeo.org/gdal/ticket/6118 and today https://trac.osgeo.org/gdal/ticket/6446
Closing as not a QGIS bug.
#8 Updated by Piers van der Torren over 8 years ago
I experience the same problem, it seems really gdal/libpoppler related, as the gdalinfo also crashes on the same pdf files.
Reported to gdal (with example file): https://trac.osgeo.org/gdal/ticket/6446
This bug is solved in GDAL 1.11.3, but not yet in Ubuntu 15.10 packaging. It should be fixed in Ubuntu 16.04.
Ubuntu 15.10, GDAL 1.11.2+dfsg-3ubuntu3, libpoppler52 0.33.0-0ubuntu3
