Comment 8 for bug 642746

Personally I suspect there may be a wider problem with reading configuration. I see other slightly similar things happening (in Lucid as well):
 * Sometimes after a reboot my CPU frequency management is delegated to the Performance governor instead of the Ondemand governor that I would normally get. However, changing the setting back manually fixes it.
 * Sometimes (aspects of) my desktop theme settings just seem to be forgotten. However, loading up the Appearance preferences is often enough to bring them back to normal.
