TiffImagePlugin.py, line 1010:
atts = dict([(k,v) for (k,(v,)) in ifd.items() if k not in blocklist])

fails on BytesPerSample = (8,8,8), since there are too many bytes to unpack.

This wasn't a problem with bilevel g3/4, but is for deflate.

Also, test what G4 does with color data. And possibly prevent that compression on anything but a mode 1 image.
