  Hum, seems that libxml2 error message got inserted at the beginning
of the XML result:

paphio:~/XML -> more ../fedora-core-test2-metadata.xml
xmlEncodeEntitiesReentrant : input not UTF-8
<?xml version="1.0"?>
<metadata xmlns="http://linux.duke.edu/md/common">
  <package type="rpm">
    <name>4Suite</name>
....

This makes the file not XML actually, no XML parser should produce
any result when parsing it.
The bug is probably related to an error in the python bindings of 
libxml2 printing to stdout instead of stderr (that was fixed last month).
The simplest is to catch the libxml2 errors with
-------------
err=""
def callback(ctx, str):
     global err
                                                                                
     err = err + "%s %s" % (ctx, str)
                                                                                
libxml2.registerErrorHandler(callback, "-->")
-------------
