Cannot mount encrypted volumes from netbook shell

[Viesturs Zariņš]

I made an luks encrypted USB pen using this guide: http://emcken.dk/weblog/archives/164-encrypted-usb-drive-in-ubuntu.html

Ubuntu recognizes this pen as encrypted drive, and mounts fine from nautilus.

However when trying to open unmounted volume from the netbook shell (under Files and Folders/Volumes), nothing happens.
If the volume is already mounted, it works.
If the volume is not mounted, but the password is remembered, it also works.

Expected behavior:
When opening encrypted volume from netbook shell, a dialog is shown that asks for password and then opens the volume.
