One thing I note is that it appears you may be doing OpenGL calls 
potentially before you get a valid OpenGL context.  On windows that can 
often wind up crashing and/or using the non-accelerated driver.  On my 
Gentoo workstation I get an Invalid Operation GL exception when I try to 
run your code, the most likely cause for that would be an invalid context.

You should likely run all of your OpenGL code in a display callback from 
wxPython.  At the very least you should "set current" in order to force 
a given context to be active.

PS, a few fixes in bzr head for the shader object log operations and the 
like, if you're using them.

Good luck,
Mike
