fretsonfire: glx issue?

[RalfGesellensetter]

dear deb gamers team,

during linuxtag berlin, I encountered fretsonfire.

I even managed to setup my gforce graphics to GLX [1] - but still 
fretsonfire refuses to run:

$ python /usr/share/games/fretsonfire/game/ViewTest.py
E
======================================================================
ERROR: testTransition (__main__.ViewTest)

    self.screen = pygame.display.set_mode(resolution, flags)
