test_set() was introduced in a bugfix

http://bugs.python.org/issue15133
https://hg.python.org/cpython/rev/117f45749359/

that I don't have on my machine (up-to-date Linux Mint 17).  When I download

https://hg.python.org/cpython/file/117f45749359/Lib/tkinter/test/test_tkinter/test_variables.py

and manually run that file I get errors similar to those you are reporting:

$ python3 test_variables.py | grep -v ok$

This leads me to believe that your tests and the tkinter shared library may 
not match. Does

$ python3 -c 'import _tkinter; print(_tkinter)'
<module '_tkinter' from '/usr/lib/python3.4/lib-
dynload/_tkinter.cpython-34m-x86_64-linux-gnu.so'>

show something suspicious?
