--- Comment #1 from Andreas Pakulat <apaku gmx de>  2009-05-30 20:08:42 ---
I can reproduce this, even though the bt is slightly different in the last few
frames of thread #1. I'm re-assigning to kdelibs/kdeui for now, as its either a
bug in xmlgui (those actions come from kate and I'm suspecting that maybe the
actions merging is not done properly when switching different kate views) or
its even a bug in Qt.

Better BT (only thread 1 as the others are fine), I'll attach the bt full
output as that clearly shows there's 0-QAction in the menu:
