Thank you for taking the time to report this bug and helping to make Ubuntu better.
We think this bug should be now fixed, can you try to reproduce it again?

In the meanwhile, I set the report as Incomplete for easier tracking, do not hesitate to set it as Fix Released if the bug is fixed for you or Confirmed again if it's still present.

merged into trunk. Thanks for your work there. Reassigning to right package too :)

didn't know about g_clear_error. Better than if (error) g_error_free (error); error=NULL;
Thanks for the tip!
