2to3 ParseError with UTF-8 BOM

[Farshid]

I'm using Python 2.6.2 and when I run the 2to3 script on a file that
contains a UTF-8 BOM I get the following error:

RefactoringTool: Can't parse <filename>: ParseError: bad token:
type=55, value='\xef', context=('', (1, 0))

If I remove the BOM then it works fine. Is this expected behavior or a
bug in the 2to3 script?
