Title: bz18429. don't crash if Expat doesn't get any data

We get the following Exception when there's no data in the .emx file:

Traceback (most recent call last):
File "miro/emusic.pyo", line 76, in _download_emx_files
File "xml/dom/minidom.pyo", line 1914, in parse
File "xml/dom/expatbuilder.pyo", line 924, in parse
File "xml/dom/expatbuilder.pyo", line 211, in parseFile
ExpatError: no element found: line 1, column 0```

We check for that message; if it's there, then we just log that there's no data
and move on.
