Ah, I forgot about that one. 

But now something interesting happened: 
With GEM_SINGLE_CONTEXT=1 the screen still stays black.

But the crash on closing the gemwindow is gone! Oh noooooo!  :)

Actually that's pretty promising in general: I was getting the crash even with
single context rendering previously.

I don't get any errors in the console:

GEM: using GEM_SINGLE_CONTEXT
GEM: Direct Rendering enabled!
GEM: GLEW version 1.5.0
GEM: Start rendering
GEM: Stop rendering

gemhead prints the usual, e.g.: 

gem_state 1
gem_state (pointer) (pointer)
gem_state (pointer) (pointer)
...

Ciao
