Version:            (using KDE 3.5.8)
Installed from:    Ubuntu Packages
OS:                Linux

In Kubuntu Hardy Heron (alpha1 to 4) when you select System Setting/User management (as well in Displays&Monitors and Windows applications) you get the following error message:

The module User Management could not be loaded.

The diagnostics is:
Library files for "libpython2.5.so" not found in paths.

Possible reasons:
  - An error occurred during your last KDE upgrade leaving an orphaned control module
  - You have old third party modules lying around.

Check these points carefully and try to remove the module mentioned in the error message etc.etc.


When you run userconfig from the command line with kcmshell you get the same dialog but more information in the terminal:
Pythonize constructor -- pid = 8592
Python interpreter initialized!

Pythonize constructor -- pid = 8592

Original exception was:

  File "/var/lib/python-support/python2.5/userconfig.py", line 19, in <module>
    from qt import *
ImportError: /usr/lib/python2.5/site-packages/qt.so: undefined symbol: PyUnicode_Type

And when you run /var/lib/python-support/python2.5/userconfig.py on its own it works.
This last one kind of proofs that kcmshell somehow gets its environment wrong.
