Re: [Qgis-developer] Segmentation fault immediately after QGIS start

2015-08-31 Thread Andreas Neumann 

Hi,

The problem is solved. It turned out, that I had the same problem back 
in 2012. Google revealed it:

https://lists.osgeo.org/pipermail/qgis-developer/2012-December/023819.html

I had to re-compile GDAL to use an external JPEG library, not the 
internal one - otherwise QGIS would crash on start. Strange, how these 
libraries interact ... The new startscreen seems to have displayed a 
JPEG file (just as the about screen). That's why QGIS crashed on these two.

Hi Andreas,

I assume the libqtwebkit-dev package comes with the source code only

It would be very valuable to have a stacktrace of the crash since that 
would point out where the issue actually is located.

If I aptitude search for webkit, I get 144 !! results and it is a bit

Could this explain the crashes I have?

With the newest master I get a segmentation fault immediately after 
starting. Even before loading a project.


Maybe this has to do with the recent start screen modifications?
