bgl and image tests requires opengl..
If libGL.so can't be loaded every gl call will result in an undef..
Opengl-extensions not available on your gfx-card will also result in an

I have seen strange crashes in the file dialog on a FC-6 linux/gtk but 
havn't been able to debug it.
It crashes far down in gtk (in libxml if I remember correctly), even if 
I just make all the calls directly in the driver. I don't know if some 
lib in emulator messes with something in gtk or if there is a pointer 
problem somewhere (probably) but it's strange I have only seen it with
the gtk native file dialog, it worked when I used the generic file dialog.
