Selection of "Server für Deutschland" not possible in Download from dropdown-list

[alex]

Binary package hint: software-properties-kde

I'm using Kubuntu 9.10. The installed version of software-properties-kde is 0.75.4.
My system language is german.

When I run

kdesudo software-properties-kde

and try to change the download server from "Haupt-Server" (=main-server) to "Server für Deutschland" (=server for germany) I get the following error:

Traceback (most recent call last):
