Using the parser module to create a parse tree succeeds, but a
subsequent tuple2ast fails, when parsing valid try/except/finally (and
try/except/else/finally) blocks. parser.tuple2ast fails with:
parser.ParserError: Illegal number of children for try/finally node.

Fixed in r67576, will be ported to all branches.
