Seeing the following and wondered if it is particular to my installation?

Automount of USB drives no longer works from console
$ ck-list-sessions
Session8:
     unix-user = '12345678'
     realname = 'joe'
     seat = 'StaticSeat1'
     session-type = ''
     display-type = 'Local'
     open = 'TRUE'
     active = 'FALSE' <== Seems to be the problem
     x11-display = ':0'
     x11-display-device = '/dev/tty1'
     display-device = ''
     remote-host-name = ''
     is-local = 'TRUE'

switch-user to the same user and active goes to TRUE and USB drives automount again.

However, that's not a good workaround as logging out from the switch-user session seems to cause ConsoleKit to crash.
Screen goes to black with a flashing cursor (i.e. no greeter screen).
