Hi Brian,

thank you for your report.

I downgraded the severity because it really does not affect everyone.

Ok, so it doesn't sound like another effect of
http://bugs.debian.org/494168 then.

This is actually quite insightful, thanks. The outer process
apparently can write to stderr (fd 2) just fine, but the subprocess
tries to write to stderr which fails. This is probably a filter or a
backend. The interesting bit is that neither "*** WARNING" nor "Please
fix your" appears anywhere in the cups source, so maybe you are using
a third-party driver?

How did you do the strace on the backend process, modified the init
script?

Can you please do:
 * rm /var/log/cups/error_log
 * set "LogLevel debug" in /etc/cups/cupsd.conf
 * try to start cups

and send me /var/log/cups/error_log and /etc/cups/cupsd.conf and
/etc/cups/printers.conf?

Thanks,

Martin
