I got this as well, and gave the resulting CoreDump an analysis. In on_bus_gotten, manager->priv->introspection_data is NULL. This can happen if gsd_xrandr_manager_stop/gsd_media_keys_manager_stop/etc is called between register_manager and on_bus_gotten.
As I'm not a gnome expert, please review the attached patch before applying - and if you think it makes sense, extend it to do media_keys_manager, power_manager, etc as well. It also adds an explicit ref/unref to make sure the manager is not a dangling pointer at this point, but I doubt this is needed. ** Patch added: "50_fix_on_bus_gotten_crash.patch" https://bugs.launchpad.net/gnome-settings-daemon/+bug/832603/+attachment/2474275/+files/50_fix_on_bus_gotten_crash.patch -- 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/832603 Title: gnome-settings-daemon crashed with SIGSEGV in g_simple_async_result_complete() Status in Gnome Settings Daemon: Incomplete Status in “gnome-settings-daemon” package in Ubuntu: Triaged Status in “gnome-settings-daemon” source package in Oneiric: Triaged Bug description: random rash after upgrade ProblemType: Crash DistroRelease: Ubuntu 11.10 Package: gnome-settings-daemon 3.1.4-0ubuntu3 ProcVersionSignature: Ubuntu 3.0.0-9.14-generic 3.0.3 Uname: Linux 3.0.0-9-generic i686 Architecture: i386 Date: Wed Aug 24 13:41:30 2011 ExecutablePath: /usr/lib/gnome-settings-daemon/gnome-settings-daemon InstallationMedia: Ubuntu 11.10 "Oneiric Ocelot" - Alpha i386 (20110817) ProcCmdline: /usr/lib/gnome-settings-daemon/gnome-settings-daemon ProcEnviron: SHELL=/bin/false PATH=(custom, no user) LANG=en_US.UTF-8 SegvAnalysis: Segfault happened at: 0x81ebf6d: mov 0x8(%edx),%edx PC (0x081ebf6d) ok source "0x8(%edx)" (0x00000008) not located in a known VMA region (needed readable region)! destination "%edx" ok SegvReason: reading NULL VMA Signal: 11 SourcePackage: gnome-settings-daemon StacktraceTop: ??
