I have also seen this with several version of Qt including 4.7 beta 1.  The 
way I trigger it is to open a non-modal dialog from a menu, then go back to 
the menu and move the mouse over the menu items.  I do not understand 
what's wrong, but it goes away if I use Qt::QueuedConnection in the 
connects for the menu.
