invalid time_zone setting causes strange stacktrace in geographic_admin

What steps will reproduce the problem?
1. install geographic_admin and make sure it is all working
2. edit settings.py to change TIME_ZONE to an invalid value eg.
TIME_ZONE='abcdefg'
3. python manage.py shell

------------------------------------------------------------------------
What is the expected output? What do you see instead?
a django python shell

instead I get a mysterious stack trace:
geo@tux:~/geographic_admin$ python manage.py shell

Please provide any additional information below.
the only settings I have changed in settings.py are the DATABASE_USER and
TIME_ZONE
when I change the timezone back to 
TIME_ZONE = 'America/Vancouver'
everything works fine.

Other commands to manage.py also give the same stack trace.
If I comment out the 'world' installed app I can get a shell as expected.
