Bug Description
How to repeat:
1) Get e.g., http://
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-
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.

Can you switch to tty and run ubuntu-bug ubiquity? or at least copy /var/log/syslog and /var/log/ installer/ * if there are any?
