I’m trying to run an existing project on a new installation of Rails  
on a Windows 7 machine. When I try to load the schema, I get:

rake aborted!  
undefined method `full\_name’ for “\377\376-”:String

I can’t figure out what is causing the error. My best guess is some  
kind of gem conflict, but various reinstallations and copious  
experimentation have failed to get to the bottom of it.

I’m running Rails 2.3.5, Ruby 1.8.7, and MySQL 5.0 and installed Ruby  
via the one-click installer. Loading the schema on another project was  
successful, so it must be something related to my specific project  
code, but I can’t see what. If anyone can help, I’d be really  
grateful.

A trace on schema:load gives:

PS C:\Projects\otwarchive\otwarchive\> rake db:schema:load --trace
