For general info on debugging, make sure to check the wiki page:

And while you are there maybe you can add some notes on your experience.

In case you want to play with the GHCi debugger, I've been updating  
the repository with the latest ghc 6.6 patches these days, so it is  
still alive and working. Unfortunately, you still will need to  
compile it yourself (just to make it clear, this means compiling a  
custom version of GHC).
