Are you sure that this is the problem? Are you sure that it's not something else?

Yes, I'm sure.

Try to convert this image: http://www.colour.org/tc8-03/images/ski_pg/Ski_TC8-03_abs.tif

It will fails to open with Acrobat Reader.

Ghostscript will report an human readable error:

File has an unbalanced >> (close dictionary).

Removing the duplicate [0.9643 1.0000 0.8251] solves the problem; since it is not valid PDF syntax.

Works for me. Attached is the patch that you should hang on Bugzilla in a new bug report.

Thanks,

Lee.
