[Qgis-developer] Segmentation fault immediately after QGIS start

Fri Aug 28 02:15:31 PDT 2015

Hi,

Regarding my crash/segmentation fault - I think this is a local issue I 
have with webkit - because when I open the about screen of an older QGIS 
version (2.10) it also crashes - and as the about screen also contains 
webkit it is the same crash behaviour than with the new startscreen.

Now - my question:

What webkit packages are actually recommended for QGIS? There are so 
many webkit packages to choose from in Ubuntu 15.05 that I am a bit lost 
which one is the correct one to use.

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

Here are the ones I have installed:
Konsole output

gir1.2-webkit-3.0
Konsole output
libkdewebkit5
Konsole output
libkf5webkit5
Konsole output
libqt5webkit5
Konsole output
libqtwebkit-dev
Konsole output
libqtwebkit4
Konsole output
libwebkitgtk-3.0-0
Konsole output
libwebkitgtk-3.0-common
Konsole output
qml-module-qtwebkit

https://github.com/qgis/QGIS/blob/master/INSTALL says I have to install 
"libqtwebkit-dev" - but maybe my libqtwebkit-dev is actually pointing to 
qt5 instead of qt4?

Could this explain the crashes I have?

Thanks for any hints on what are the correct packages for Webkit in 
Ubuntu 15.04.
