I got this crash, probably due to a bad image. The code in ImageStripper.py that calls PIL is currently in a except IOError, but should probably be in a bare except to catch any and all errors from PIL. In my case I got an IndexError.
I could make this change, if there is consensus and once Sourceforge
lets me get at the spambayes repository.
