Summary: RecenFilesList mysteriously containing str with NULL bytes

Initial Comment:
Please note that I have only seen this a few (3) times. I 
am unable to reproduce this. 

When I attempt to start IDLE from within Windows it 
does not bring up any window. When I tried to start it 
from the command line, I received this error:

C:\Python23\Lib\idlelib>python idle.py
Traceback (most recent call last):
  File "idle.py", line 23, in ?
    idlelib.PyShell.main()
  File "C:\Python23\lib\idlelib\PyShell.py", line 1271, in 
main
    flist.new()
  File "C:\Python23\lib\idlelib\FileList.py", line 62, in new
    return self.EditorWindow(self, filename)
  File "C:\Python23\lib\idlelib\PyShell.py", line 80, in 
__init__
    EditorWindow.__init__(self, *args)
  File "C:\Python23\lib\idlelib\EditorWindow.py", line 186, 
in __init__
    self.UpdateRecentFilesList()
  File "C:\Python23\lib\idlelib\EditorWindow.py", line 595, 
in UpdateRecentFilesList
    rfList=self.__CleanRecentFiles(rfList)
  File "C:\Python23\lib\idlelib\EditorWindow.py", line 620, 
in __CleanRecentFiles
    if not os.path.exists(path[0:-1]):
  File "C:\Python23\lib\ntpath.py", line 256, in exists
    st = os.stat(path)
TypeError: stat() argument 1 must be (encoded string 
without NULL bytes), not str

With a little print statement of what "path" is in this 
case, I found out that it is the following:

['\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00
\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00
\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00
\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00
\x00\x00\x00\x00\x00']

I have worked around the problem by clearing out rfList 
on line 619 of EditorWindow.py. I'm guessing I'm getting 
into some sort of weird state but it is worth mentioning.
