When stepping through the package wizard it prompts for a filename. If one
actually provides a filename, an exception is generated and neither the "Next"
nor "Previous" buttons work. Seems to be trying to treat the file as XML and
running into problems parsing it. Should really handle data files separately
from metadata files.

Towards that end, I suggest that FileSystemDataStore makes a separate subdir for
data and metadata (which has the added benefit of avoiding a bunch of sax parse
errors when searching). Maybe profiles/username/data and
profiles/username/metadata?
