I get the error

ValueError: unknown locale: en_NG

after I create a new Django 1.5 project, run "python syncdb" and attempt to define a superuser. This was also a bug in Django 1.4 when it was first released but was eventually fixed.

Thanks for the traceback.

Python-related bugs:

Related Django ticket: #16017

We should definitely catch ValueError in get_system_username.

As you can see by comparing the patches, I chose a different fix for stable (minimal potential impact) and master (bit of refactoring).
