When I try to access User Management in system settings, I get the following error:
http://wstaw.org/m/2011/01/27/plasma-desktopxO1747.jpg

Reproducible on all user-accounts.

Same with printer configuration.
I saw a bug report about that for the beta. It was said it was fixed in stable. But it is not. Any workaround?

Both these modules use the KDE python bindings. Please ensure the KDE 4 Python bindings are installed and up to date.

I have python-kde4 installed.
version is 4:4.5.5-0ubuntu1ppa1

should it be 4.6? is it a bug in ubuntu packaging?

I had that problem too, but then I used "sudo apt-get update && sudo apt-get upgrade && sudo apt-get dist-upgrade" at the terminal and there where other updates you have to install.

Thanks, there were many updated packages in ubuntu repos today. The second update solved the issue with not working user management.

You're welcome
