In my Rails app, I am occasionally getting a class definition missing  
error. I see this error in my logs, and every once in a while run into  
it myself, but not in a way I can reproduce. The error looks like:

/data/web/findit/Umlaut/config/…/lib/hip3/bib\_searcher.rb to define  
Hip3::BibSearcher

But, bib\_searcher.rb DOES define Hip3::BibSearcher! And the error is  
not easily reproducable, it seems to crop up in mysterious places.

Has anyone run this sort of thing? Any ideas? Thanks for any.

Jonathan
