Hi,<br>
<br>
The problem is solved. It turned out, that I had the same problem
back in 2012. Google revealed it:<br>
<a class="moz-txt-link-freetext" href="https://lists.osgeo.org/pipermail/qgis-developer/2012-December/023819.html">https://lists.osgeo.org/pipermail/qgis-developer/2012-December/023819.html</a><br>
<br>
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.<br>

Hi Andreas,<br>
<br>
I assume the libqtwebkit-dev package comes with the source code
only and that the same source code can be compiled against qt4 or
qt5, so there is no separate package (just guessing though).<br>
<br>
It would be very valuable to have a stacktrace of the crash since
that would point out where the issue actually is located.<br>
<br>

Hi,<br>
<br>
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.<br>
<br>
Now - my question:<br>
<br>
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.<br>
<br>
If I aptitude search for webkit, I get 144 !! results and it is
a bit overwhelming.<br>
<br>
Here are the ones I have installed:<br>

Do you have any idea on what may be wrong? If no, I can go back in git
history and try to find the commit that makes my QGIS crash on start.
