Bug#497492: cupsd: Child exited on signal 13!

Yes, the description in the title sounded different. I haven't read the
details though.
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?
I would assume it is all part of the following message:
sam lintory # /usr/sbin/cupsd -f
*** WARNING *** The program 'cupsd' uses the Apple Bonjour compatibility layer of Avahi.
*** WARNING *** Please fix your application to use the native API of Avahi!
*** WARNING *** For more information see <http://0pointer.de/avahi-compat?s=libdns_sd&e=cupsd>
No, nothing related installed outside of Debian. Not that I know of anyway...
How did you do the strace on the backend process, modified the init
script?
strace -ff cupsd
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?

Hmmm. Maybe this is more significant when I run it with -F and it works:

I have no idea what this error code -65537 is, what DNS-SD is, or if it
is in anyway related. I am very suspicious in any case, it happens about
the right point. Out of time now, will investigate again tomorrow.
Thanks
