Dumping core when there is no terminal server, instead of exiting 
gracefully, might be considered a bug.

Beside Paul's comment, I suggest running with 2.7.latest and tk 
8.6.latest if at all possible to get tkinter and tk bug fixed.

Also, Menubutton is considered obsolete for Window level menus, so it 
may not be maintained as well.  Just use Menu if at all possible.
