Even simpler. I meant you are calling it direectly or indirectly from
frameSomething, i.e., above your call in the call stack a
frameSomething. The GLEW stuff only really matters on Windows anyway.

I haven't used FBO's so far, but other things, e.g. GLSL shaders do
work.
I'm not sure what the problem is, but I don't think it is the
threading/extension handling per se. To me it seems that there is an
error during FBO creation.
