On Fedora 21, the tests pass (Python 3.4.1 and latest dev version).

On Fedora 23, I see:

$ python3 -V
Python 3.4.3
$ python3 -m test -ugui test_tk test_ttk_guionly test_idle
[1/3] test_tk
[2/3] test_ttk_guionly
[3/3] test_idle
All 3 tests OK.

$ ./python -V
Python 3.6.0a0
$ ./python -m test -ugui test_tk test_ttk_guionly test_idle
[1/3] test_tk
[2/3] test_ttk_guionly
[3/3] test_idle
test test_idle failed -- Traceback (most recent call last):
