i have a strange problem …  
i successfully deployed my application and the mongrel cluster runs fine  
… now on the application level i get the following error when i request  
the app via the browser (it looks like not all files have been loaded  
automatically, because also on a console i get the same error):

uninitialized constant ActionView::Base::CompiledTemplates::Q2

Q2 is a class which lives in models …  
all that stuff work fine on my dev machine
