[Fabio Marconi]

This bug is fixed after reboot the upgraded session with ubiquity-dm working too
wait till tomorrow build to mark as fixed.

Hallo
Testing ubuntu 20120711.2 .
Boot regularry, and the first screen appear, then as usual black screen instead of plymouth and ubiquity-dm.
Only background and upper panel appearing with a message error of ubiquity telling that it encounter an unrecoverable error and the live session will be started, click on OK.
This message error popup at live session just started.
Also clicking on the Ubiquity' icon on the launcher, it crash immediatly with same message.
