Summary: crash inside glGetBoolean(GL_TEXTURE_2D)

Initial Comment:
http://bugzilla.gnome.org/show_bug.cgi?id=552981 is receiving lots of duplicates, and it seems to be a PyOpenGL issue.
Kindly asking for investigating here:

Message:
Sorry this bug didn't get addressed last year.  I can't reproduce the
behaviour on Ubuntu amd64, the traceback suggests that the NonesHandler was
registered as being a return-type handler, which should not be possible on
current bzr head (at least, I don't see how it could happen).

Message:
A workaround is to install python-numpy (tested on Ubuntu 9.04).

Message:
Same for me with glGetDoublev(GL_VIEWPORT)

OpenGL.__version__ = '3.0.0b6'

This is on Ubuntu 9.04

Message:
Same for me on debian lenny with 3.0.0~b6-3, going back to b3-1 resolves
the problem.

Message:
I have the very same problem, but with glGetInteger(GL_DEPTH_BITS). This
only happens with b6, going back to b5 makes the error disappear.
