What's a good way to handle fatal errors - missing packages, .ui files not compiled, Qt DLLs or shared objects not found, etc. - in a PyQt app (or other Python app)?

Imported like so: from <module> import * Inside my module, there exist functions whose purpose is to set global variables in the main program.

I'm creating a Django-powered site for my newspaper-ish site. The least obvious and common-sense task that I have come across in getting the site together is how best to generate a "top articles" list for the sidebar of the page.
