This bug was fixed in the package cups - 1.6.1-0ubuntu11.4
---------------
cups (1.6.1-0ubuntu11.4) quantal-proposed; urgency=low
* debian/cups.logrotate: Do not remove CUPS' log files while the CUPS
daemon is running. Stop CUPS, move the files, and then start it again.
This avoids crashes during the log rotation process (LP: #1086019).

Bug description:
Every day I get a 'System Problem Detected' dialog that says that
cupsd has crashed. The symptom is similar to the one described in bug
1034045.
I expected this would be fixed by cups 1.6.1-0ubuntu11, but I have
that version installed and the errors persist. The test case in bug
1034045 does not result in an immediate crash of cupsd. Specifically,
this does not produce a crash on my system:
1. Run 'sudo rm -f /var/crash/_usr_sbin_cupsd.0.crash'
2. Run 'sudo service cupsd restart'
3. Verify that a new /var/crash/_usr_sbin_cupsd.0.crash file has been created
(and if on a desktop, that a new crash notification has been shown).
[IMPACT]
For CUPS users who activate the "Show printers shared by other
systems" in the server settings of system-config-printer or in the
CUPS web interface, so that they automatically get shared remote CUPS
printers listed in print dialogs CUPS crashes regularly, typically
once a day triggered by logrotate, popping up an Apport dialog to
upload the crash info to Launchpad. Otherwise all is working
correctly, there is only the annoying crash report.
[TESTCASE]
Activate "Show printers shared by other systems" in the server
settings of system-config-printer or run the command
cupsctl --remote-printers
I am not sure whether there must be actually a remote printer to
trigger the crash. So on another computer in the same local network
(or on a virtual machine if you do not have a second computer) create
a CUPS queue and share it. Activate "Published shared printers
connected to this system" in the server settings of system-config-
printer or run the command
cupsctl --share-printers
on that computer. Now observe for some days. Probably you will get a
crash report once a day.
With the proposed package the logrotate script is improved to not take
a way log files from CUPS while it is running. It stops CUPS, moves
the log files, and after that starts CUPS again. This way CUPS stops
crashing during the logrotate once a day, so the system will behave
normally now. Printing does not trigger the crash, so print jobs are
always executed correctly.
You can test whether crash reports still work with the proposed
package by triggering an artificial crash running the command
sudo killall -11 cupsd
Check whether the crash report process of Apport gets triggered, but
DO NOT post the generated bug report on Launchpad. Remove
/etc/apport/blacklist.d/cups (remainder from earlier proposed package)
if this does not happen and try again.
[Regression Potential]
None. No change in any executable which could cause a regression.
