Status changed to 'Confirmed' because the bug affects multiple users.

[BlueCase (bluecase)]

The problem seems only happen when you upgrade from 12.04.

I am experiencing this bug on a new install of 12.10, not an upgrade. It just started after several weeks of working properly.

[jandro (thejandroman)]

Disregard previous comment, fix is in the original bug report.
