Greetings,
I recently upgraded a machine from PIL 1.1.5 to 1.1.7 and ran into a couple of
buglets. One was the "'Nonetype' object has no attribute 'bands'" one with a
fix found here:
http://hg.effbot.org/pil-2009-raclette/changeset/fb7ce579f5f9
The other I've not found any references to in the list archives (or
elsewhere): while saving an image in PNG format PIL threw an exception
"compress() argument 1 must be string or read-only buffer, not None". I'm
wondering if anyone else has run into this one, and whether this is a
reasonable way to work around it:
