[gtkmm] FileChooserDialog dies in c'tor

[Vladislav Grinchenko <3rdshift comcast net>]

This is probably a long shot - but I'm at the end of 
my wits on this one.

An application crashes in FileChooserDialog c'tor 
allocated on a stack like so:

void foo ()
{
crash>  Gtk::FileChooserDialog f ("Select Deck File", 
  		  Gtk::FILE_CHOOSER_ACTION_OPEN);
    ...
}

It happens with one particular installation of gtkmm2 2.4.4.
Everywhere else I tried (2 other machines) the code works
as expected.

The trace follows. Perhaps someone might have an idea or
a suggestion of any kind, or could recognize the problem.

thanks in advance,
-Vlad
