[Qgis-user] QGIS Segmentation fault

[Blumentrath, Stefan]

He, he, thanks for the hint...

Running QGIS through gdb ("gdb ./output/bin/qgis") and then calling "bt" gave "No stack".

However, when I ran  just "./output/bin/qgis" I got:

src/app/main.cpp: 428: (main) [0ms] Starting qgis main

I am running QGIS through VNC (which X Server :4 refers to). Yet, maybe the issue is due to missing restart after kernel update?

Cheers,
Sefan
