Automounting of USB devices and CD-ROM in KDE fails, with this Konqueror error:
  "Permission Denied: Not in active session"

It used to work perfectly with FC6, but is broken since I've upgraded to F7.

Running Fedora 7 + updates, and specifically: ConsoleKit-0.2.1-2.fc7
kdebase-3.5.6-12.fc7

SELinux is disabled. Logging in and out, restarting the ConsoleKit service, and
rebooting don't fix this.

Mounting directly via /usr/bin/mount works fine.

The above 100% reproducible on my machine. I don't have a fresh F7 install at hand.

In one case, I used the "Start New Session" option in KDE to open a 2nd parallel
session, and then then mounting worked from the *2nd* session. However, I'm now
unable to reproduce this effect.

$ ck-list-sessions
Session4:
        uid = '501'
        realname = 'Foo Bar'
        seat = 'Seat1'
        session-type = ''
        active = TRUE
        x11-display = ':0'
        x11-display-device = '/dev/tty7'
        display-device = ''
        remote-host-name = ''
        is-local = TRUE
        on-since = '2007-06-17T15:56:29Z'

and XDG_SESSION_COOKIE is set to a 61-char string.
