ubiquity crashes when "something else" is selected

[Len Ovens]

Tried both manual from use whole drive and something else. Both times the something else manual partition editor comes up then the installer crashes. The something crashed icon comes up and when selected asks if I would like to file a bug I select continue and get asked to include the config file with my password in it (I haven't even got to passwords yet). Then it goes away and no bug report.

While we might have fixed usb sticks installation. Manual partitioning is now having woes.

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

[Greg Faith (gregfaith)]

Same results with crashes on "do something else" qa iso-testing Lubuntu desktop 12.10 amd64 and i386.

[Scott Kitterman (kitterman)]

Also failed on Kubuntu, but the proposed fix, http://paste.ubuntu.com/1284298/ produced a completed, working install.

[Launchpad Janitor (janitor)]

This bug was fixed in the package ubiquity - 2.12.14

---------------
ubiquity (2.12.14) quantal-proposed; urgency=low

  * Add extra checks when determining boot parameter for grub_default,
    which prevents crashing the installer upton entering manual
    partitioning (LP: #1067566)
