A stack trace doesn't constitute an error report. You need to tell us how to generate the error.

Working on the assumption that the problem is just 'an app without a', I can't reproduce this.

  • Description modified (diff)

Sounds like (though details of the traceback have changed in the interim): Prior to the introduction of module_has_submodule, things found in INSTALLED_APPS that did not have a __path__ were just ignored. The check was originally put in for "odd things" like eggs (though it's not necessary for eggs); the original person who hit a problem which caused the check to be added actually had a completely unnecessary non-app listed in INSTALLED_APPS. If there's a valid reason for having things in INSTALLED_APPS that don't have a __path__ then we can probably deal with it in module_has_submodule, but I haven't heard that reason yet. The one person who originally ran into the issue when the __path__ check was put in acknowledged it was caused by an error in their INSTALLED_APPS.
