This only happens on a system that is installed as a ubuntu server and then ubuntu-desktop is added using tasksel. Also, it only happens when the GUI is run through a VNC session. I have reproduced this in a VM after initially seeing it on a physical server.
Other notes:
* The user is the primary user of the system and is in the admin group.

* I think that this is related to polkit behavior in Maverick. The workaround in bug #221363 does not appear to work in Maverick.
