Selecting "Something else" also gives unexpected behaviour since although it shows the VGs, nothing appears to be deletable via this screen, and each VG is shown twice with the 2nd entry indented, like this:
/dev/mapper/myhost-root /dev/mapper/myhost-root /dev/mapper/myhost-swap_1 /dev/mapper/myhost-swap_1 /dev/sda /dev/sda1 /dev/sda5
The "used" column shows "unknown" for all indented entities.
