I'm trying to convert a Django 1.2 site to a 1.4 site.  So there's lots of 
changing old generic views to class-based generic views, and the apps all 
go up one level so lots of changes to imports, but in each case so far it's 
it's been quite easy to narrow down the problem to a line in my code, and 
fix it.  Until I got to this:

So basically I have have no clue what part of *my* code could be causing 
this as there's no reference to my code.  How would I find out how to trace 
this back to something I can change.  I imagine I can pore through the 
Django sources but I'm not really a Python programmer, I just know enough 
syntax to write Django code.

Any ideas?
