valgrind output:
(kde trunk r1001942, qt4.5 from git)
It looks like the KMenu is destryoed while it's being pressed
(probably because there is reentrency in the event loop)
Just a guess, but maybe the edit toolbar dialog is called with exec() instead
of show()
my qmenu.cpp:1007 activationRecursionGuard = false;
