Bug #3430: Error parsing PubMedCentral XML files

It seems that there is an error parsing locally downloaded PubMedCentral xml (extension nxml) files. Using the code 

@
from Bio import Entrez
handle = open('nihms83342.nxml')
records = Entrez.parse(handle)
for record in records:
    print record
@

the following error occurs (copied from iPython), even though the XML header contains the declaration


---------------------------------------------------------------------------
NotXMLError                               Traceback (most recent call last)
<ipython-input-5-e78d8d3c3888> in <module>()
      2 handle = open('nihms83342.nxml')
      3 records = Entrez.parse(handle)
----> 4 for record in records:
      5     print record

/Library/Python/2.7/site-packages/Bio/Entrez/Parser.pyc in parse(self, handle)
    229                         # We did not see the initial <!xml declaration, so
    230                         # probably the input data is not in XML format.
--> 231                         raise NotXMLError("XML declaration not found")
    232                 self.parser.Parse("", True)
    233                 self.parser = None

NotXMLError: Failed to parse the XML data (XML declaration not found). Please make sure that the input data are in XML format.

The XML file in question is attached.
