I've retitled the bug to focus on the failure to parse the XML file (there is
no problem in Bio.Entrez.efetch as far as I can tell).  For example,

>>> from Bio import Entrez
>>> result = Entrez.read(Entrez.efetch(db='snp', id='9996597', retmode='xml'))
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "Bio/Entrez/__init__.py", line 286, in read
    record = handler.run(handle)
  File "Bio/Entrez/Parser.py", line 95, in run
    self.parser.ParseFile(handle)
  File "Bio/Entrez/Parser.py", line 131, in startElement
    if object!="":
UnboundLocalError: local variable 'object' referenced before assignment


This may be an NCBI bug, try this:

>>> from Bio import Entrez
>>> print Entrez.efetch(db='snp', id='9996597', retmode='xml').read()
...

Then copy and paste the XML into a validation site like
http://www.validome.org/xml/validate/ where I see an error.  On the other hand,
http://validator.w3.org/#validate_by_input seems happy with only a warning.
