The first attempt gave

$ python3.5 -m test -ugui test_tk test_ttk_guionly test_idle
[1/3] test_tk
[2/3] test_ttk_guionly
test test_ttk_guionly failed -- Traceback (most recent call last):
  File "/usr/local/lib/python3.5/tkinter/test/test_ttk/test_widgets.py", 
line 947, in test_tab_identifiers
    self.fail("Tab with text 'a' not found")
AssertionError: Tab with text 'a' not found

[3/3/1] test_idle
2 tests OK.
1 test failed:
    test_ttk_guionly

In subsequent repetions all tests completed without error.

My completely unbased guess is that my system is too slow so that the Tab 
was not yet there when the check was performed.
