I can't reproduce this (I tried on an amd64 mostly-sid system with ghostscript and libgs8 8.71~dfsg2-9 and cups and libs 1.4.4-7+squeeze1). Any ideas? If no other obvious ways to make progress come up, here are some hints: - Please provide a PDF file and exact command line to reproduce it on a machine without the SLP driver installed. (The instructions would have to include installing the SLP driver if that's the only way to reproduce it.) - If you look at "dmesg" output, does it say which DSO segfaulted? - Rebuilding ghostscript with DEB_BUILD_OPTIONS='debug nostrip' and getting a backtrace by running gs with "gdb --args" as described at [1] would also be helpful. - Anyone who can reproduce this can take over what I was going to try, which is finding the patch that fixed the problem at git://git.ghostscript.com/ghostpdl.git using "git bisect".

Bug#651736: ghostscript: segfault when using cups device for rastering w/ SAFER and Seiko PPD
Package: ghostscript Version: 8.71~dfsg2-9 Severity: normal ghostscript 8.71 segfaults when invoked by CUPS (via the pdftoraster filter) to print to a Seiko Smart Label Printer (SLP) using the PPD provided by Seiko (at www.siibusinessproducts.com). The offending ghostscript command (with standard input from pstopdf|pdftopdf) is /usr/bin/gs -dQUIET -dPARANOIDSAFER -dNOPAUSE -dBATCH -sDEVICE=cups -sstdout=%stderr -sOutputFile=%stdout -I/usr/share/cups/fonts -r203x203 -dDEVICEWIDTHPOINTS=236 -dDEVICEHEIGHTPOINTS=68 -dcupsBitsPerColor=1 -dcupsColorOrder=0 -dcupsColorSpace=3 -scupsPageSizeName=AddressSmall -c -f - If the PARANOIDSAFER option is removed, the command succeeds, but it still fails with SAFER instead. The above command succeeds when using the precompiled gs 9.04 for linux-x86_64 from downloads.ghostscript.com, but all else from my Squeeze system.
