gnome-settings-daemon crashed with SIGSEGV in g_str_hash()

it's crashing is gsd-ubuntu.c

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.

Not quite sure why this is breaking exactly yet, but I am working on it and will have a fix uploaded in the next day or so.

Thanks for the feedback and for looking into it, Rodney!
Can you reproduce the crash?
If not I can try to setup a VM to see if I can reproduce it there.

I have extended my Ubuntuone subscription by 20 GB but the crash still happens. So this seems unrelated to tripping the quota.

Please also see bug #554280 which I believe this to be a duplicate of.

Currently the crash doesn't happen anymore. Not sure if something needed to propagate. I'm currently having issue with file syncing (probably due to my ISP) so I can't easily test if tripping the new quota makes the issue reappear.

I retract the part of comment #9 that suggests this may be a duplicate of bug #554280 ... it just happens that the crash happens at the same place.
