Different crash

With this patch applied I get different crashes at two different places. I'll
attach the backtraces as files because they are longer this time.

There's one speciality in WineD3D that may be related to the crashes: When
WineD3D loads, it creates a GL context and attaches it to a hidden X11 Window.
This context is used to read the OpenGL extension string, OpenGL limits and
other GL characteristics. No rendering is done(that's undefined on a hidden
window), but we do try to load some textures to test PBO and FBO functionality
to detect a few known bugs on some implementations. We have to do this because
we have to be able to give information about our capabilities before a Direct3D
device is created(D3D device ~ GL context). I'll make a Wine log to see how far
the WineD3D init gets.

I don't know the code, but it seems to me that the patch just tries to hide the
crash rather than addressing the core issue.
