14698	django.utils.module_loading.module_has_submodule yields false positives	Łukasz Rekucki	nobody	"The way I found this is a bit crazy, so I'm not going to describe it all, but the 2 important things are:

  # I have some explicit relative imports.
  # I wanted to make a template library named the same as the application it contains. 

This generally should work (tried on a fresh project), but failed with a weird error in my project: ""'currencies' is not a valid tag library: ImportError raised loading company.templatetags.currencies: No module named currencies"". Of course there is no such module, because it's on ""currencies.templatags"" application.

So after some debuging it turned out that module_has_submodule returns a false positive. This is because it checks {{{ if name in sys.modules }}}. To be honest, I didn't know about this, but it seems that Python sometimes also stores import misses by puting a None in to that dictionary.
