Unfortunately the problem is not resolved. I worked around it by manually installing kubuntu-default-settings as per your suggestion in bug 218064, however, this should be added as a hard dependency (not Recommends) if it is necessary in order to have a working environment.

Well, yes. It is only temporary until this bug is fixed.
