Hmm... that's unfortunate.
What platform are you on? If Windows, then I believe that PIL is
statically linked against LibTIFF and that particular libtiff wasn't
compiled with certain options (CCITT formats or something.) (in 1999
that was true, I found a post from Fred here:
http://mail.python.org/pipermail/image-sig/1999-June/000755.html)
If it's a one-time thing, there are ways of converting the TIFF to a
different encoding. I use the libtiff tifftools command tiffcp:
tiffcp -c none infile.tif out file.tif
which will decode into a non-compressed tiff.
Otherwise, you might be out of luck (or have to change some of the
libtiff options.)
If you put your tiff file somewhere where I can download it, I'll try
reading it with the alternatives that I have on my system and let you
know what works...
