stellarium crashes on 9.0-CURRENT

[Rainer Hurling]

For some weeks now I am not able to start astro/stellarium (versions 
10.3 and 10.5) any more. Immediately after starting I only get a core 
dump, nothing else.

It seems like this behaviour appeared after the latest update of KDE / QT.

I am running recent 9.0-CURRENT (amd64) with x11/nvidia-driver. Other 
OpenGL programs like astro/celestia and astro/openunivers work like a charm.

Looking at the core dump with gdb gives me the following output (btw. it 
seems to be difficult to build stellarium with debugging symbols, any 
hints?):

This looks like a problem with OpenGL (QT / NVidia?). I have no clue 
what to do next ...

Any help is really appreciated. Thanks in advance,
