Description of problem: If a puppet module is malformed Pulp shows the user an exception. Malformed could be that the full module name is missing an author (0 dashed is full module name) or that the name portion of the full module name contains additional dashes. The second case is one example in the traceback below for the puppet module named "windows_xmltask-0.0.3".


How reproducible: Always, as long as puppet modules on puppetforge are malformed as described above.


Steps to Reproduce:
1. Add a puppet repo setup to sync puppet forget with no filter
2. Perform a sync
3. Observe the traceback

Actual results:
Most of it sync's, but you'll receive output like this:

    puppet_importer:

I expect two behaviors:
1. Pulp should handle named puppet modules without exactly one dash in them more gracefully.
2. If it absolutely can't handle the puppet module a coded exception or nicer message should be shown to the user.
