Debugging a process

I've got an Epson printer I've set up with CUPS. Unfortunatley it came out,
that the program CUPS uses internally (rastertoprinter) gets some kind of
lockup right after ending the page - it starts to eat up 100% CPU; CUPS gets
the message "Page finished", but the job stays there - and the printer
device (lpt0) is in use.
Well, so I did "gdb", attached to the PID, typed "bt"... nothing. Just a few
lines with addr no and question marks.
I've recompiled said program (and the library it depends on) with "-g" in
It came out, that the binary was stripped during install. I've installed
unstripped binary. Still the same thing.
Googled. Nothing really useful found.
At this point, I feel pretty lost - I've thought, that I know, what I have
to do when I want to have debugging info compiled in, and how to use gdb
(I know enough to get the backtrace, which is sufficient).
Any help / any ideas?
