Description:
I cannot umount my luks encrypted usbstick. I created a udev rule so
that the stick appears on /dev/cryptostick. When I plug it in, I get a
dialog asking me for my luks password, and mounts it fine. Then 2
devices appear in the drive-mounter: One for the usbstick, and one
called 'usbdrive'. Only the latter one offers me an option to unmount,
but fails with the message:

'umount: /media/usbdisk is not in the fstab (and you are not root)'

unmounting with 'pumount /media/usbdisk' on the shell works for me
without any problem.
