Traceback (innermost last):

    PyShell.main()
  File "/usr/lib/idle/PyShell.py", line 612, in main
    fixwordbreaks(root)
  File "/usr/lib/idle/editorWindow.py", line 606, in fixwordbreaks
    tk.call('tcl_wordBreakAfter', 'a b', 0) # make sure word.tcl is loaded
TclError: extra characters after close-quote

I can't see what is problem...
It seems that fixwordbreaks() are source of problem...
