Comment 6 for bug 744383

I'm currently experiencing this issue also.

It happens reliably when my UbuntuOne storage and music folders trip together the UbuntuOne quota.

I find it strange that the ubuntuone-client can cause gnome-settings-daemon to crash. I would imagine that gnome-settings-daemon should be fixed in a way that other processes cannot crash it. But I haven't looked at the integration to be sure.

Please let me know if you need further information.
