AW: [gtkmm] Segfault when calling the MenuItem superconstructor.

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

Hi!

I will run some tests, first I am doing it with MenuItem then with others.
But for MenuItem I have some (maybe interesting) results:

I am using some shell-script to repeatingly compile a C++ File
and afterwards starting the resulting executable.

The funny thing is that the SEGFAULT only occurs on certain sizes of the
MenuItem-object.
