This bug report was moved from ESP GhostScript (http://www.cups.org/espgs/str.php?L2302). As ESP GhostScript is discontinued and currently merged into GPL GhostScript, the bug will be tracked here now. The excellent automatic crash reporter of Ubuntu Linux (Feisty) has caught a segfault in ESP GhostScript 8.15.4 and generated a complete symbolic traceback for it. See https://launchpad.net/ubuntu/+source/gs-esp/+bug/93891 The user is working on 32-bit PC and has an Epson Stylus CX3600 on USB. Driver is the CUPS raster version of Gutenprint 5.0.0.99.1 (default driver in Ubuntu). The job causing the failure was a .png image printed out of Eye of Gnome. I have made an LSB binary package of GPL GhostScript with the ESP GhostScript functionality (esp. the "cups" output device) merged in and asked the user to try this one. Here is everything about the state of the merger: http://www.linuxprinting.org/download/printing/esp-gpl-ghostscript-merge/README
8.1x is obsolete. Please test with 8.56 GPL Ghostscript If the problem still occurs, attach a sample file and command line that reproduces the crash. Closing the bug as "LATER" until the above is satisfied.
So we must wait for the original poster at Ubuntu to answer my testing request.
After nearly 12 years, I think we can assume the original reporter isn't going to show up.
