[New-bugs-announce] [issue17613] IDLE error

[Raymond Hettinger]

New submission from Raymond Hettinger:

Running ILDE with 2.7.4 RC 1 on Mac OS X 10.8 and with ActiveTCL 8.5.13 using "python -m idlelib.idle", I object the following traceback messages.  I'm unsure what events are triggering it:

Traceback (most recent call last):
  File "/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/lib-tk/Tkinter.py", line 1470, in __call__
    return self.func(*args)
  File "/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/lib-tk/Tkinter.py", line 531, in callit
    func(*args)
  File "/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/idlelib/ColorDelegator.py", line 153, in recolorize
    self.recolorize_main()
  File "/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/idlelib/ColorDelegator.py", line 186, in recolorize_main
    next = self.index(mark + "+%d lines linestart" %
  File "/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/idlelib/Delegator.py", line 10, in __getattr__
    attr = getattr(self.delegate, name) # May raise AttributeError
AttributeError: 'NoneType' object has no attribute 'index'
