[BioPython] ClustaW problem upwards Biopython 1.43

[Stefanie Lück]

Hi!

I just releazed, that a ClustalW alignment gives an error message under Biopython 1.44 and 1.47 whereas under 1.43 everything works fine. 

The message is the following (example of the tutorial):

Traceback (most recent call last):
  File "I:\Final\pair_align.py", line 90, in pair_align
    alignment = Clustalw.do_alignment(cline)
  File "C:\Python25\Lib\site-packages\Bio\Clustalw\__init__.py", line 79, in do_alignment
    status = run_clust.close()
IOError: [Errno 0] Error

Does someone know what's the problem?

Kind regards
Stefanie
