Description Ken Sharp 2011-10-21 14:33:41 UTC 
Created attachment 8034 [details]
offending file

The attached file raises a warning that the Indexed space has a short lookup table for every Indexed space in the document.

I'm not convinced this is correct, and I'm wondering if the PDF interpreter is getting confused by using the stream length of a compressed stream to determine if there is sufficient data for the lookup table.

If I decompress the file suing either pdfclean or pdftk the warnings go away....

Fix indexed color space processing code that miscalculated
the length of an index table when the table stream was compressed.
