ok, then, If we aren't going to handle this with gtkmm functionality what
should be done?
1. Make a note in documentation about order of menu child destructors.
2. Assign issue to GTK to let them check and fix it.

I am not sure that 2nd way even has a place here, because GTK programmers=
 never
will go that way of menu object destruction as it is possible in GTKMM.

Regards,

If this is indeed the problem (I have not yet investigated) then we would=
 want
to either=20
a) Fix GTK+
b) Do some kind of workaround in gtkmm.

Simply documenting a problem would be the least desirable solution.

OK. I have applied that, with some small changes (see the ChangeLog). It =
still
needs a fuller review.

I am concerned about the pkg-config dependency on the unix print library.=
 We
need to somehow #ifdef that, I think.
