Package: cups
Version: 1.4.5-2
Severity: important
After attempting to print the web page at
http://en.community.dell.com/support-forums/desktop/f/3514/t/17880588.aspx,
the list of available printers stopped after showing 'print to file'
and only after looking around did I notice that the cups daemon was
not running. Restart attempts failed to bring the daemon up because
the old pid file was still around. After starting the daemon it kept
failing, not always with a segfault.
After cleaning out the cups spool totally ('rm -rf *' from
'/var/spool/cups/') and restarting cups with debug turned on
I still experience some cups segfaults, most recently when trying
to display active and/or completed jobs.

I am attaching the cups log in gzipped format.
