When entering ubi-partman then going back to the previous page (here ubi-wireless), parted_server crashes

[Stéphane Graber]

With current ubiquity trunk, leaving ubi-partman immediately after we get the list of partitioning options crashes parted_server with the stacktrace below:

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

On Kubuntu 13.10 ubiquity (ubi-partman) crashes when clicking the back button in the disk setup if there is no wlan interface.
Tested on a VirtualBox VM
