Unable to mount any device or partition as non-root user

[Rainer Rohde]

I am not sure if I am filing this against the correct app.

With today's Oneiric update, I am suddenly no longer able to mount any of my partitions or external drives / devices. I get the following error message: "Unable to mount XYZ - Not authorized" (where XYZ is the name of the device or partition).

I am able to mount those devices as root just fine, however.

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

This affects me as well... I'm running the 64-bit edition on my laptop. Connecting a USB drive or even trying to access the CD drive will come up with an error saying "Not Authorized". The strange thing is, when I right click on the drive and press "Eject" or "Safely Remove" from the menu, the error STILL comes up. I have no access whatsoever. This all started for me after I set up the 3D cube with Unity, which is known to have glitchy side-effects anyway.
