User Management module is not part of the KDE Software Compilation. Please file the bug to https://bugs.launchpad.net/ubuntu/

*** Bug 226754 has been marked as a duplicate of this bug. ***

Ubuntu refuses to accept this bug report:

"Das Problem kann nicht gemeldet werden:
Dies ist kein echtes Ubuntu-Paket"

Which means: Can not report this problem. It's not a real Ubuntu package!

KDE Platform Version: 4.4.00 (KDE 4.4.0)
Qt Version: 4.6.1
Operating System: Linux 2.6.31-20-generic i686
Distribution: Ubuntu 9.10

This is a valid issue with the python bindings.

The file affecting this is /usr/share/pyshared/PyQt4/uic/uiparser.py
The problem is line 184:

bg_name = bg_i18n.string

Which needs to read:

bg_name = str(bg_i18n)

Making this correction allows User Management to launch without error.

I was able to report tis bug at launchpad with the help of some great hints
from IRC: https://bugs.launchpad.net/ubuntu/+source/kdebindings/+bug/522309

@Paul
That's an unrelated crash with similar symptoms. It should be fixed in the lastest kdebindings upload to Kubuntu.

Giving more clear title

Kubuntu 9.10 amd64
KDE 4.4
