Note thst the proposed package is applying a workaround which is specific to Quantal. The fix in Raring will be removing the patch for forward-porting CUPS broadcasting/browsing and replacing it by an extra daemon for Avahi browsing, making use of CUPS' Avahi broadcasts. The daemon will be part of the cups-filters package and I have nearly completed its development. So please process this SRU without the Raring task being "Fix Released".
** Description changed: 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, + 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.
