[Pedro Villavicencio (pedro)]

Thank you for taking the time to report this bug and helping to make Ubuntu better. Is the issue reproducible with gnome-settings-daemon 3.1.90 or newer? There's no recent comments on this report indicating that, could you please test and comment back?. Thanks again and we appreciate your help.

setting back to New it got a recent duplicate and the stacktrace shows it tries to unref a null gvariant which is probably a bug

[Pedro Villavicencio (pedro)]

is this still an issue with latest package on Oneiric?

[Ezio de Mauro (pancro)]

Yes, at least for me, I've just done a dist-upgrade and I'm still affected.

[Sebastien Bacher (seb128)]

could you describe what you do to get the issue?
