Thank you for your bug report

Tim, that seems to be a new issue in the 3.8 update, could you have a look to it?

I found that replacing it with the one from GNOME's PPA actually rectifies the issue entirely. Comparing the sources of theirs and Ubuntu Gnome's may help a lot in triaging this bug.

[Isiah Meadows (impinball)]

I take that back...that definitely did not change on a consistent basis for the better.
