[cups.bugs] [MOD] STR #2031: pdftops Seg Faults when filtering certain pdfs

[Hin-Tak Leung]

[STR New]

Here is gdb on fc5 against the cups-shipped pdftops (poppler-shipped
pdftops doesn't segfault). It looks like the code is trying to do a
dictionary look up on the "Creator" field of the pdf, which does 
not exist on v1.2 pdf's (this is a very old-style pdf).
