Title:
  ubiquity kde frontend is broken in current kubuntu daily builds

Status in “ubiquity” package in Ubuntu:
  Fix Released
Status in “ubiquity” source package in Precise:
  Fix Released
Status in “ubiquity” source package in Quantal:
  Fix Released

Bug description:
  How to repeat:

  1) Get e.g., http://cdimage.ubuntu.com/kubuntu/precise/daily-
  live/20120924.1/precise-desktop-amd64.iso

  2) Try to boot it in a VM (qemu/KVM or virtualbox should do fine)

  3) Experience the crash

  
  Please don't ask stacktrace etc since I can't get any (it refuses to load any debug information,
  --pdb doesn't seem to work either).

  A little debugging with --debug shows:
  kubuntu-ubiquity(3341)/kdeui (kdelibs): Session bus not found

  12.04.1 livecd works fine. The major change between that version and now was KDE
  4.8.4 -> 4.8.5 and a small update in dbus-x11 (but my hunch is that the first is the culprit).

  I think the problem is that KDE added a new way to (try to) access the session bus
  under the hood, at a time when ubiquity doesn't expect and so is running as root,
  causing the problem.

  strace shows many -EAGAINs in what seems to be D-bus communication before
  the crash, which seems to support this.
