Correction:  It dumps core on FreeBSD 10.2 but on CentOS 6 I get:

Traceback (most recent call last):
  File "/usr/local/TundraWare/bin/twander.py", line 5464, in <module>
    UI = twanderUI(UIroot)
  File "/usr/local/TundraWare/bin/twander.py", line 2152, in __init__
    self.CmdBtn = Menubutton(self.mBar, text=COMMANDMENU, underline=0, state=DISABLED)
  File "/usr/lib64/python2.6/lib-tk/Tkinter.py", line 2710, in __init__
    Widget.__init__(self, master, 'menubutton', cnf, kw)
  File "/usr/lib64/python2.6/lib-tk/Tkinter.py", line 1932, in __init__
    (widgetName, self._w) + extra + self._options(cnf))
_tkinter.TclError

This code runs fine on physical FreeBSD/CentOS/Debian servers, Rasperberry PIs running
Raspbian, OSX, VirtualBox and VMware Workstation Linux servers, Windows .... so I suspect
this is somehow VPS related but not sure where to start.
