[BioPython] problems when parsing blast output

[Alessandro S. Nascimento]

Hi all,

I am trying to write something very simpleto parse very extense blast 
output file. But when I try something as described in web's cookbook i 
get the following error message:


asn at frodo:~/fool/programming/python$ ./teste_asn.py
Traceback (most recent call last):
  File "./teste_asn.py", line 10, in ?
    b_record = b_iterator.next()

line 1342, in next
    return self._parser.parse(File.StringHandle(data))

Does anyone have any idea?
