OK, I think I know why this is happening, though I can't reproduce myself. I have uploaded gnome-settings-daemon 3.4.2-0ubuntu12 to quantal-proposed. I'd really appreciate testing by those that get this crash. I'm confident, but not certain I've got the right fix.
[Gory details if you happen to know the code] The idletime signals are firing after the power manager is stopped. idletime is a singleton that hands out references to itself every time it is 'created'. And stop() is expecting a mere unref() to disconnect the signals. But it doesn't if idletime has been reffed more times. So this patch manually disconnect the signals we set up. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to gnome-settings-daemon in Ubuntu. https://bugs.launchpad.net/bugs/971353 Title: power : gnome-settings-daemon crashed with SIGSEGV in gnome_rr_screen_get_dpms_mode Status in Gnome Settings Daemon: New Status in “gnome-settings-daemon” package in Ubuntu: Confirmed Status in “gnome-settings-daemon” source package in Precise: Confirmed Status in “gnome-settings-daemon” source package in Quantal: Confirmed Bug description: spontaneous crash at startup ProblemType: Crash DistroRelease: Ubuntu 12.04 Package: gnome-settings-daemon 3.4.0-0ubuntu2 ProcVersionSignature: Ubuntu 3.2.0-20.33-generic 3.2.12 Uname: Linux 3.2.0-20-generic x86_64 ApportVersion: 2.0-0ubuntu2 Architecture: amd64 CasperVersion: 1.312 Date: Mon Apr 2 12:11:23 2012 ExecutablePath: /usr/lib/gnome-settings-daemon/gnome-settings-daemon LiveMediaBuild: Xubuntu 12.04 LTS "Precise Pangolin" - Beta amd64 (20120328) ProcCmdline: /usr/lib/gnome-settings-daemon/gnome-settings-daemon ProcEnviron: LANGUAGE= TERM=linux PATH=(custom, no user) LANG=en_US.UTF-8 SegvReason: reading NULL VMA Signal: 11 SourcePackage: gnome-settings-daemon Title: [power]: gnome-settings-daemon crashed with SIGSEGV in gnome_rr_screen_get_dpms_mode() UpgradeStatus: No upgrade log present (probably fresh install) UserGroups: adm cdrom dip lpadmin plugdev sambashare sudo To manage notifications about this bug go to: https://bugs.launchpad.net/gnome-settings-daemon/+bug/971353/+subscriptions -- Mailing list: https://launchpad.net/~desktop-packages Post to : [email protected] Unsubscribe : https://launchpad.net/~desktop-packages More help : https://help.launchpad.net/ListHelp
