I'm able to replicate this only when at least one configuration revision has been created. However, the specific exception message I receive is

'ConfigRevision' object has no attribute 'BANNER_BOTTOM'

The fix for this issue should include a test which attempts to export the system configuration with at least one ConfigRevision in place.
