E.g. http://code.google.com/p/go/ causes this error.
Traceback (most recent call last): File "/var/local/allura/ForgeImporters/forgeimporters/google/tasks.py", line 37, in import_project_info extractor.get_license(c.project) File "/var/local/allura/ForgeImporters/forgeimporters/google/__init__.py", line 175, in get_license project.trove_license.append(trove._id) AttributeError: 'NoneType' object has no attribute '_id'
Since it doesn't specify what those multiple licenses are, we can't pick any. So I think we just need to leave the license blank on the Allura side and avoid the error.
