[Samuele Battarra]

Package: fretsonfire-game
Version: 1.3.110.dfsg2-1
Severity: grave
Justification: renders package unusable

Dear Maintainer,

Game fail to start with this output:

Traceback (most recent call last):
  File "./FretsOnFire.py", line 74, in <module>
      engine = GameEngine(config)
  File "/usr/share/games/fretsonfire/game/GameEngine.py", line 194, in __init__
      self.data = Data(self.resource, self.svg)
  File "/usr/share/games/fretsonfire/game/Data.py", line 48, in __init__
      self.loadSvgDrawing(self, "star1",   "star1.svg", textureSize = (128, 128))
  File "/usr/share/games/fretsonfire/game/Data.py", line 106, in loadSvgDrawing
      drawing  = self.resource.load(target, name, lambda: SvgDrawing(self.svg, fileName), synch = True)
  File "/usr/share/games/fretsonfire/game/Resource.py", line 157, in load
      return l.finish()
  File "/usr/share/games/fretsonfire/game/Resource.py", line 68, in load
      self.result = self.function()
  File "/usr/share/games/fretsonfire/game/Data.py", line 106, in <lambda>
      drawing  = self.resource.load(target, name, lambda: SvgDrawing(self.svg, fileName), synch = True)
  File "/usr/share/games/fretsonfire/game/Svg.py", line 552, in __init__
      self.texture = Texture(bitmapFile)
  File "/usr/share/games/fretsonfire/game/Texture.py", line 202, in __init__
      self.loadFile(name)
  File "/usr/share/games/fretsonfire/game/Texture.py", line 206, in loadFile
      self.loadImage(Image.open(name))
  File "/usr/share/games/fretsonfire/game/Texture.py", line 213, in loadImage
      string = image.tostring('raw', 'RGBA', 0, -1)
  File "/usr/lib/python2.7/dist-packages/PIL/Image.py", line 686, in tostring
      "Please call tobytes() instead.")
Exception: tostring() has been removed. Please call tobytes() instead.

Replacing 'tostring' with 'tobytes' in function loadImage in Texture.py solves the problem.
