AW: AW: [gtkmm] Segfault when calling the MenuItem superconstruct or.

["Hopfes, Harald" <Harald Hopfes Hopfes sysde eads net>]

Hi!

It is derived very often in the following classes:

checkmenuitem.h:class CheckMenuItem : public MenuItem
imagemenuitem.h:class ImageMenuItem : public MenuItem
radiomenuitem.h:class RadioMenuItem : public CheckMenuItem
separatormenuitem.h:class SeparatorMenuItem : public MenuItem
tearoffmenuitem.h:class TearoffMenuItem : public MenuItem
