I realized a bug introduced with the patch, one I fixed together with 
David some years ago ;)

If a widget that is in the actioncollections list of associated widgets 
gets deleted the collection has a dangling pointer and you get crashes 
later on.
The solution we had in kde3 (aka, known to work) was to listen to the 
QObject::destroyed (QObject *=0) signal and remove the widget from the 
list doing a single d->associatedWidgets.removeAll(obj);
