"Skeleton" test window decoration that should enable blur behind

Version:           unspecified (using Devel) 
OS:                Linux

Since KDE 4.6.x blur effect does not work behind a KCommonDecoration, even if it is transparent and sets the "AbilityUsesBlurBehind" property.

Reproducible: Always

Steps to Reproduce:
Install the attached test decoration

Actual Results:  
No blur behind decoration, even when blur effect is enabled (and works behind Plasma panels)

Expected Results:  
Blur works

This affects deKorator and Smaragd theming engines.

The decoration has also to support the AbilityUsesAlphaChannel to get blur behind the decoration. I just added it to the source code and everything get's nicely blurred.
