ubiquity crashed with KeyError in partman_dialog(): 'method_choices'

[Brian Murray]

I was futzing around in the advanced / expert partitioner and ran into this crash.

I had create a boot partition and then a physical volume for encryption. I then pressed revert and was trying to change the encryption partition or create a new partition in it when it crashed.

Ah, this is easy to reproduce here. Create a "physical volume for encryption", then double click on the new partition that appears.

This bug was fixed in the package ubiquity - 2.12.13

---------------
ubiquity (2.12.13) quantal-proposed; urgency=low

  [ Dmitrijs Ledkovs ]
  * Do not allow to edit locked partitions via double click in the Gtk
    Treeview. (LP: #1057690)

  [ Colin Watson ]
  * Fix "Mangement" typo (thanks, Yuri Chornoivan; LP: #1067228).
  * Update translations from Launchpad.

  [ Stéphane Graber ]
  * Add an extra parameter to grub_default so that the UI can force it to use a
    specific device rather than scan for / and /boot.
    Update Gtk and Kde code to pass that parameter when in auto mode.
    (LP: #1066173)
  * Automatic update of included source packages: base-installer
    1.122ubuntu13, partman-auto 103ubuntu4.
