Before all, my KDE is in spanish, so, i try to translate all to english, so, excuse me for my language errors.

DESCRIPTION:
I go to the Network module of the KDE Control Center (of Internet and Network section). I have two ethernet interfaces: 'eth0' -that are disabled and not configured yet- and 'eth1' -that are enabled and configured via DHCP from my ISP-. So, I switch to 'Administrator mode' and when I select the 'eth0' interface and i click in the 'Configure Interface' the window says 'Loading...' ('Cargando...' in my spanish KDE) and then the crash.

Here is the information:

Short description:
