I assume you rebuilt VTK.  I've been using 4.4.x for a while and
things seem to work fine for me.  The most common case of failure with
the Tk widgets is when you build VTK with a different version of
libtcl/libtk than the one used by _tkinter.so.  So, I'd recommend that
you first run ldd on _tkinter.so (it should be in
/usr/lib/pythonX.Y/lib-dynload/) and check to see if you built VTK
4.4.2 with the same exact version of the libraries.  If you did not do
this, reconfigure CMake to use the correct version and build it again.
This usually fixes most problems of this kind with the Tk widgets.

HTH.
