Policykit doesn`t acept changes under 11.3 and KDE 4

hallo folks!

The policykit under opensuse 11.3 and KDE4 doesn´t react on value changes.
I want to change the value:

org.freedesktop/upower/The DeviceKit-power Project/Hibernate the system

Every time when I changed a value it is reset immediately when I chose another value, even as root.

Look at this screen shot:
