You could do worse than start with `M-x toggle-debug-on-error RET',
assuming from the above that you've not already got that?

Read the "Debugging" section in the Emacs Lisp manual.

Debugging Lisp

[Peter Lee]

I have a very rudimentary understanding of lisp but I would like to
find out where in w3m.el I'm failing.

Is the typical way to just insert messages in the suspect function to
find where it's breaking ?  Any hints on debugging lisp?

Thanks Tim, I tried that. It didn't change anything, I'm guessing I
have to figure out why w3m is exiting with status 1 when called via
emacs-w3m, but works fine when called from shell.

Debug on Error enabled
Reading http://emacs-w3m.namazu.org/...done
Cannot retrieve URL: http://emacs-w3m.namazu.org/ (exit status: 1)

I'll have a look at the debugging section in the lisp manual.
