I think this is related to the old style exceptions which were being used in
Bio.PDB, see http://www.python.org/dev/peps/pep-0008/

> When raising an exception, use "raise ValueError('message')" instead of

> continuation characters thanks to the containing parentheses.  The older
> form will be removed in Python 3000.

It looks like the old form was removed in Python 2.6 (or I have mis-identified
the problem).

I've switched all the exception raises in Bio.PDB in CVS, and made the
exceptions into proper classes, which I hope will address this bug under python
2.6.
