Switch Kontact application language in KDE4.5

Hi,

Since I installed KDE SC4.5, Kontact refuses to switch language.

Even though, in KDE system settings, I set the following languages in order of preference en_gb / fr / en_us, when I go in Kontact/Help/swith language, I only have the possibility to have en_us, en_us, and en_us (yes, 3 times).
Of course, other applications do work as expected (at least I tried with dolphin).

I also tried to change language for the whole kde, but kontact remains in en_us. Tried to remove kontactrc, no change.

Does anybody have this problem, or a hint for resolving it?

I think the language files for the KDEPIM applications are missing in the
packages:

Yes you are right. I checked my installation and there is no *.mo files for the PIM applications.
There is also a bug report:
