Hi Django'ers,
I get a strange bug, which seems to be a problem/conflict between PIL
(Python Imaging Library) and the ImageField model field. I have a
standard ImageField, but when a user tries to upload an ico file
(created either at http://www.html-kit.com/favicon/ or http://www.favicon.cc/),
django crashes with this traceback (see below).
At a Python prompt I can use PIL to open an ico file just fine, but
django further asks PIL to decode the file, and somewhere in that
process it fails and the error isn't caught. I can't find any problems
on the web regarding PIL and its handling of ico files. Has anyone
ever come across this, and/or does anyone have any suggestions? I
figure I can just use a FileField, since the data then wouldn't be
validated by PIL, but other ideas/workarounds are welcome.
Thanks :) Michael
