XDG prepends /rofs/ to paths

You can see this by doing
sudo kde-config --path mime
on the live cd

The reason why this happens is because the Kubuntu CD still _seems_ (I don't know at the moment) to use unionfs or some other flavor instead of the more modern and stable aufs (another unionfs).

UnionFS has/had the bug that mmap'ed files are directly loaded through the affected layer, such entries like /proc/self/exe are wrong, which not only leads to problems with daemon stopping (start-stop-daemon), but also to this issue, as KDE programs use 4th the own prefix PATH from /proc/self/exe to determine possible KDE locations.

Possible solution: Switch Kubuntu Live CD to use aufs.

In general (from my Knoppix experience) the switch is not more than installing the aufs module and changing the mount command to us br= instead of dirs= (or vice versa).
