I've got a similar problem in boson, where we use a 
KFileDialog::getSaveFileName() to store a playfield. Once this call returns 
(no matter whether the user clicked ok or cancel) KMainWindow::queryExit() 
gets called, because QApplication::aboutToQuit() is emitted.
This makes my program pretty much unusable.

Your patch fixes the problem.
