menu item doesn't work with focus in sidebar

[https://me.yahoo.com/postrockrob#52e3a]

When the focus is in a sidebar (e.g. the Debug Log), selecting a menu item can result in:

 File "/data2/home/rob/src/peppy/peppy/lib/multikey.py", line 1598, in OnMenu
    self.foundMenuAction(evt)
  File "/data2/home/rob/src/peppy/peppy/lib/multikey.py", line 1669, in foundMenuAction
    action, evt = self.findKeystrokeActionFromMenuAction(action)
  File "/data2/home/rob/src/peppy/peppy/lib/multikey.py", line 1701, in findKeystrokeActionFromMenuAction
    keystroke = self.findKeystrokeFromMenuAction(action)
  File "/data2/home/rob/src/peppy/peppy/lib/multikey.py", line 1629, in findKeystrokeFromMenuAction
    raise KeyError
KeyError

Seems to be only those menu items that don't have a keystroke accelerator. One reliable method of reproducing the error is Transform -> Whitespace -> Tabify
