Just a wild guess here. Is your module named the same as your theme? If so, change one of them.
Shouldn't we try to fix this in D8 by warning the user of the conflict with a drupal_set_message in the admin/modules page? Or perhaps fix the API so that it knows themes/foo is different from modules/foo.
