Buildbots are unhappy. Example:

http://buildbot.python.org/all/builders/x86%20Ubuntu%20Shared%203.x/builds/11437/steps/test/logs/stdio


======================================================================
ERROR: test_name_mapping (test.test_pickle.CompatPickleTests) [(('tkinter.filedialog', 'FileDialog'), ('FileDialog', 'FileDialog'))]
----------------------------------------------------------------------
Traceback (most recent call last):
  File "/srv/buildbot/buildarea/3.x.bolen-ubuntu/build/Lib/test/test_pickle.py", line 241, in getmodule
    return sys.modules[module]
KeyError: 'tkinter.filedialog'

During handling of the above exception, another exception occurred:
