Fix Memory leak related to Content Menu 

From Qt4.7 on, the contextmenu of
QTextEdit/QPlainTextEdit/QLineEdit/QLabel/QMainWindow etc using
QMenu::popup() instead of QMenu::exec(), but the
setAttribute(Qt::WA_DeleteOnClose) does not work, as QMenu::close()
isn't called when the menus disapper. And this causes a memory leak.

This is a side effect of b7af368e86874d71ffc9071c9ef009814d6a3467
