Nautilus unable to mount external disks - says not authorized to admin user

[Robbt]

Basically after upgrading my beta of 11.10 today I am no longer able to click on an external hard drive to mount it. This was working before whatever updates came down 9/14-9/15. It says not authorized in the bottom of the dialog after displaying the message Unable to Mount Diskname. I have an administrator user account that is automatically logged in. Shortly after logging in the keychain password dialog pops up but this doesn't affect the ability to mount external hard drives.

1. Description: Ubuntu oneiric (development branch)
Release: 11.10

2. nautilus:
  Installed: 1:3.1.90-0ubuntu3
  Candidate: 1:3.1.90-0ubuntu3
  Version table:
 *** 1:3.1.90-0ubuntu3 0
        500 http://us.archive.ubuntu.com/ubuntu/ oneiric/main amd64 Packages
        100 /var/lib/dpkg/status

3. I expected it to mount the external disks either automatically or when I clicked on them through the nautilus interface.
4. It gave me the error above "Unable to mount Diskname" Not authorized."

Rebooting has had no affect on this.

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

Happenes to me as well, after upgrading packages today.
