SVN commit 768811 by dfaure:

Patch from Aurélien which brings the empty actions (like KWin actions) back.
He wrote:
"I had to rework the way the kcm initializes itself.
"The new implementation asks KdedGlobalAccel for the list of components, then for
"the list of actions for each component. To do so it adds two methods to
"KdedGlobalAccel: allComponents() and allActionsForComponent(). I also had
"to remove all the "remove empty shortcuts" code from KdedGlobalAccel.
