Steps to reproduce:
Create an extended attribute (e.g. for a user) with arbitrary values. The input field "Overwrite existing widget" in the UMC tab expects the internal name of the  univention.admin.property. If a different name is provided, the following traceback occurs if the user module is opened:

This should be sanitised, either by refusing to create the extended attribute if the correct univention.admin.property cannot be found or by simply ignoring the malformed value and contuing without overwriting a widget.
