Good idea -- it gave me an answer that's no answer at all, except to suggest
that the problem lies within Firefox, not CUPS. Here's what I got:

pwa@suillus:~> firefox
./ line 131: 14691 Segmentation fault "$prog" ${1+"$@"}
pwa@suillus:~> firefox
*** glibc detected *** corrupted double-linked list: 0x09a97460 ***

I suppose I could send that off to the Firefox folks, but it might not help

dmesg had nothing relevant, but .xsession-errors ended with this:

I [28/Apr/2006:23:17:34 -0400] Job 77 queued on 'LaserJet5' by 'pwa'.
I [28/Apr/2006:23:17:34 -0400] Started filter /usr/lib/cups/filter/pswrite
(PID 14940) for job 77.
I [28/Apr/2006:23:17:34 -0400] Started filter /usr/lib/cups/filter/pstops (PID
14941) for job 77.
I [28/Apr/2006:23:17:34 -0400] Started backend /usr/lib/cups/backend/socket
(PID 14942) for job 77.

That looks normal to me.

Does any of this suggest anything to you?
