The version of the package fretsonfire is 1.2.451.dfsg-2... when i try to launch it, it crashes and doesn't run. if it could help, this is the output when i try to start if from the console:

    self.video.setMode((width, height), fullscreen = fullscreen, multisamples = multisamples)
  File "/usr/share/games/fretsonfire/game/Video.py", line 68, in setMode
    self.screen = pygame.display.set_mode(resolution, flags)
