The prob is the
KNewMenu* m_newMenu
pointer since it will still point to the mem-address the KNewMenu* was on and didn't got set to NULL if the m_newMenu-instance got deleted. That in turn means, that each place that accessed the m_newMenu will probably deal with an invalid (aka deleted dangling) KNewMenu-pointer and crash.

Following should fix it (QPointer sets m_newMenu to NULL if the KNewMenu* got deleted);
