Lucid: KDE 4.4.5 update lead to inconsistent system

[Klaus Layer]

Binary package hint: libkdecore5

Today a really big bunch of fixes to update to KDE 4.4.5 was released. After applying the fixes, apt-get reports that it holds back the update for the packages kde-l10n-de kde-l10n-engb. If I try to use

apt-get install kde-l10n-de kde-l10n-engb

to install the updates, I get the following error:

Die folgenden Pakete haben nicht-erfüllte Abhängigkeiten:
  kde-l10n-de: Hängt ab: libkdecore5 (>= 4:4.5.0) ist aber nicht installierbar
  kde-l10n-engb: Hängt ab: libkdecore5 (>= 4:4.5.0) ist aber nicht installierbar
E: Kaputte Pakete

Translated to english:
The following packages have unresolved dependencies:
  kde-l10n-de: depends on: libkdecore5 (>= 4:4.5.0) cannot be installed
  kde-l10n-engb: depends on: libkdecore5 (>= 4:4.5.0) cannot be installed
E: broken packages

Any idea how to resolve this?

Thanks
