      I downloaded Python 3.0.1 and installed on Vista. I opened IDLE and it
      worked fine. I went into the Preferences to change the keybindings on
      the history scrollers. I changed history-next to Ctrl+Down Arrow,
      though when I pressed OK it listed only Control as the binding. I then
      tried to change history-prev to Ctrl+Up Arrow, but when I pressed OK,
      it gave an error that that binding was already taken. The program then
      crashed. Since then whenever I try to open IDLE, the pythonw.exe
      process appears in my Task Manager briefly, but then it exits, and I
      never see any other evidence the program has opened. The command line
      still works fine. I tried repairing the installation, uninstalling,
      restarting the computer, and removing the leftover registry keys for a
      completely clean install, but nothing has worked to be able to reopen
      the program.

      Reproduced with the console python.exe.
      Click an item in the list on the right to choose the key ("down arrow")

      Exception in Tkinter callback

AttributeError: 'filter' object has no attribute 'append'

Then it is still possible to save these settigs, but the binding
contains event=="Control", and IDLE fails on startup:

      Thank you for the patch. I have applied it (which is to say, swapped out

      return filter(None, modList)
for
return [mod for mod in modList if mod]

      in keybindingDialog.py), but the problem persists. python.exe continues
      to load fine, but pythonw.exe still fails at startup.

      The incorrect settings have been saved in your %USERPROFILE%\.idlerc
      directory. Try deleting the idle-extensions.cfg there.

      BTW, "pythonw.exe" is not IDLE. It's a plain python interpreter without
      a console. When used with no argument it can only exit quickly...

      To see the IDLE error messages, I often type this in a console window:
      c:\python30\python.exe -m idlelib.idle

      r71998 Thanks for the patch!

      backport to 30-maint.

      If OP has further problems getting installation working, delete .idlerc
      directory.

      Modification to "customer key set" would make IDLE fail to start

      To re-produce:
      1, Start IDLE, and switch to Preference -> Keys;
      2, Make modification to the key binding;
      3, Click Apply, then click OK
      4, repeat above steps.
      The 2nd time to click OK would not get any response.
      But this is not the nightmare. Now quit IDLE and restart IDLE. But IDLE
      cannot restart.

      I believe that bpo-5707 is still exist in Ver. 3.1.1 for Mac OS X.

      OS: Mac OS X 10.6.1
      Python version: 3.1.1

      The error message from console of Mac OS X is attached as following:

      The patch fixed a real issue, the difference return of filter in 3.x versus 2.x. Bad key bindings came up in bpo-11437 and bpo-13864 also.

      Amaury's patch has already been applied in (d31be8c9c8a2).

      GUO's description does cause an error. TclTk does not allow "<Control>" by itself to be bounded. This underlying cause for that error is addressed in bpo-6739

      I think this issue should be closed.
