F10 system-config-services does not respond when enabling or disabling a service

[tux]

when i try to use system-config-services to enable a service it does not 
respond.

I am running KDE 4.1.3 on Fedora 10. this worked with no problems on F9. 
I was logged on as root.

i ran it from terminal and got the following error message:

Traceback (most recent call last):

as a workaround I used chkconfig to set things the way i wanted, however 
I thought someone might want to look at it. just in case.

Thanks.
