ubi-partman crash during Quantal daily install on Panda board

[Carla Sella]

I was installing this Daily image of Quantal on a Panda board: http://cdimage.ubuntu.com/daily-live/20120901/quantal-desktop-armhf+omap4.img.
After clicking on the continue button on the screen Preparing to install Ubuntu ubi-partman crashed, see attached picture.
I clicked on "Try again" but the window in the picture came back again.
The second time I clicke on "Continue anyway", installation continued to the timezone selection, keyboard selection, "Who are you" window and the slides, I was never asked were to install.

I interrupted install after quite a while and some "temperature alert before registers are calculated" messages.
I'm attaching /va/log/syslog before shutting down.

Read I this correct that this is a B-tree file system(btrfs) installation approach?(Not, that this is a bad think).

This bug was fixed in the package ubiquity - 2.11.28

---------------
ubiquity (2.11.28) quantal; urgency=low

  * Fix display of installation medium mounted grid. (LP: #1044717)
    Also used pylint to find check for undefined/missing attributes in the
    ubi-partman.py. Needs integration into build system.
