Crashes when cliking into the interface on f13 x86_64

[cryos]

This might be distribution related. However, I can reproduce this with the f13 package as well as the vanilla 1.0.1 version from the homepage. As soon as you click into the main window the atom is drawn but then it crashes.

I'm experiencing something similar on Arch linux 32 bit w/ gcc 4.5.0. Backtrace:

pRadius issue was fixed; however it is not related to original issue because it was inroduced in master, not 1.0

Gregor: try to change Qt style, it may help in some cases

At least in f13 this was an issue that could be solved by switching from nouveau to the nvidia driver. Also if one uses wireframe it works. Switching to any other display mode is fine as long as you don't click into the interface. After you had a look you switch back to wireframe and can work normally. However, as said above with the nvidia driver everything works normally. No i need to get it running in f14 there it might be the qt issue. Need to find time.

Gregor: if someone tells you that Nouveau supports stable OpenGL, ignore him :)

Your case was added to Avogadro FAQ. Thanks!

Closing this bug. I would love to figure out what we trip in some of the less well behaved drivers. I have not tried Nouveau recently, but last time I tried the OpenGL support was not great.
