According to the error_log, Ghostscript or hpijs crashes with a segmentation fault. I have copied the Ghostscript command line from your error_log and run it with some arbitrary PDF files. On Jaunty I can reproduce the segmentation fault and according to /var/log/syslog it is a segmentation fault in hpijs. On Karmic Ghostscript completes its job, but produces a lot of warnings:
prnt/hpijs/hpijs.cpp 389: unable to set key=Quality:SpeedMech, value=1
Shiyun, Dave, Aaron, can someone of you look into what fixed the segmentation fault in hpijs (and perhaps provide a patch) and also have a look at what causes the warning in Karmic's HPIJS?
Thank you for your error_log.
