Most probable cause:

You've got a mistyped $c->model(...) or c.model(...) declaration somewhere
which is falling through to Catalyst's regex search, and -was- originally
finding the right class because of that but the addition of the extra class
has caused the hash order for the search to change and now you aren't.

Likely candidates are either a typo or missing DB:: off a DB::Foo-style
DBIC::Schema model reference.
