Bug#505477: partman hangs if you press "Go Back" after warning message
This might be a partman-lvm issue instead, I'm not quite sure.
When doing manual partitioning, selecting a physical lvm partition and pressing
Enter the following message is displayed with a red background:
"Partition in use
No modifications can be made for the partition #6 of device IDE1 master (hda)
for the following reasons:
In use by LVM volume group vg1"
If you select "Go Back" in this dialog, an empty blue screen is displayed.
Killing partman did not seem to help (although I might have been killing the wrong stuff).
Pressing "Contine" returns me to partman, like I expected "Go Back" would.
