The test file (same as 2178 in the bug 688678).

Suggested patch

I think the problem surfaced after
    http://ghostscript.com/pipermail/gs-cvs/2006-August/006716.html .

The cycle that applies filters uses a "null" filter name as a flag that there
are no (more) filters. When this pseudo-name is looked into "filterstoremove",
now we (correctly, I understand) get a "typecheck"; before, "<dict> null known"
was simply returning "false".

Reminder: many more patches affecting pdfinflt.ps are waiting on, or are 
referenced from, bug 687796 "pdfinflt.ps creates an incomplete PDF". In 
particular http://bugs.ghostscript.com/show_bug.cgi?id=687796#c7 changes the 
method used to apply filters, and the problem described in the current bug 
report doesn't appear anymore.

assign to Alex to see if the patches on bug 688786 fix the issue.

Comment 5 Alex Cherepanov 2006-09-09 14:48:03 UTC

I confirm that this problem does not occur with the final version of
pdfinflt.ps from bug 687796, comment #16. I'm closing this bug report 
as a duplicate.
