Bug Description

Open IDLE for Python 3 on Ubuntu 16.04 (idle3 3.5.1-3) and click Options -> Configure IDLE.
The menus of IDLE stop responding and the terminal shows the following message:

    - Issue #26811: gc.get_objects() no longer contains a broken tuple with
      NULL pointer.
    - Issue #20120: Use RawConfigParser for .pypirc parsing, removing support
      for interpolation unintentionally added with move to Python 3. Behavior
      no longer does any interpolation in .pypirc files, matching behavior in
      Python 2.7 and Setuptools 19.0.
    - Issue #25745: Fixed leaking a userptr in curses panel destructor.
    - Issue #26881: The modulefinder module now supports extended opcode
      arguments.
    - Issue #23815: Fixed crashes related to directly created instances of
      types in _tkinter and curses.panel modules.

      instead of silently return incorrect result.
    - Issue #26881: modulefinder now works with bytecode with extended args.
    - Issue #26711: Fixed the comparison of plistlib.Data with other types.
    - Issue #24114: Fix an uninitialized variable in `ctypes.util`.

      against no_proxy to be case-insensitive, and to not match unrelated host
      names that happen to have a bypassed hostname as a suffix.
    - Issue #26634: recursive_repr() now sets __qualname__ of wrapper.
    - Issue #26804: urllib.request will prefer lower_case proxy environment
      variables over UPPER_CASE or Mixed_Case ones.
    - Issue #26837: assertSequenceEqual() now correctly outputs non-stringified
      differing items (like bytes in the -b mode).
      This affects assertListEqual() and assertTupleEqual().
    - Issue #26041: Remove "will be removed in Python 3.7" from deprecation
      messages of platform.dist() and platform.linux_distribution().
    - Issue #26822: itemgetter, attrgetter and methodcaller objects no longer
      silently ignore keyword arguments.
    - Issue #26733: Disassembling a class now disassembles class and static
      methods.
    - Issue #26801: Fix error handling in :func:`shutil.get_terminal_size`,
      catch :exc:`AttributeError` instead of :exc:`NameError`.
    - Issue #24838: tarfile's ustar and gnu formats now correctly calculate name
      and link field limits for multibyte character encodings like utf-8.
    - Issue #26657: Fix directory traversal vulnerability with http.server on
      Windows.
    - Issue #26736: Used HTTPS for external links in the documentation if
      possible.
    - Issue #22359: Disable the rules for running _freeze_importlib and pgen
      when cross-compiling. The output of these programs is normally saved
      with the source code anyway, and is still regenerated when doing a
      native build. Closes: #820509.
    - Issue #21668: Link audioop, _datetime, _ctypes_test modules to libm.
    - Issue #26799: Fix python-gdb.py: don't get C types once when the Python
      code is loaded, but get C types on demand. The C types can change if
      python-gdb.p...

So it says here that a fix was released a month ago but nothing happens even if I continuously update my system. As reported in http://bugs.python.org/issue26673 , the problem lies in the lack of a config file. Here is a quick workaround: Save the following file as $HOME/.idlerc/config-main.cfg

https://svn.python.org/projects/python/trunk/Mac/IDLE/config-main.def
