Desktop effects is selected, Window decorations is displayed.

Version:           unspecified (using KDE 4.5.1) 
OS:                Linux

I'm experiencing a strange behaviour when trying to configure KWin Desktop Effects. When opening the control module from an opened window (upper left button in KWin default decoration -> "Window settings" or something similar) I get that the default selected item is "Desktop effects", but the opened module is "Window decorations". If I click again on the item "Desktop effects" the opened module doesn't change, while if I click on another item the module changes. Now, after changing module, if I click on "Desktop effects" I finally get the "Desktop effects" module.

Reproducible: Always

Steps to Reproduce:
Open "Window settings" from a window.

Actual Results:  
"Window decoration" module is active.

Expected Results:  
Selected (in this case "Desktop settings") module is active.

Using KDE 4.5.1 with Qt 4.7.0 on Arch Linux with kernel 2.6.35
