in my case it's at line 38 (but I see line 79 might trigger the same problem):
/.../rdkit/Chem/Draw/cairoCanvas.pyc in __init__(self, image, size,
ctx, imageType, fileName)
36 self.imageType=imageType
37 if image is not None:
---> 38 imgd = image.tostring("raw","BGRA")
39 a = array.array('B',imgd)
40 stride=image.size[0]*4
apparently the BGRA encoder wasn't yet available in PIL 1.1.6.
In any case, also on this machine, I could quickly override the
library available from the system with an updated one installed in a
virtualenv, and this fixed the issue with the image file generation.
