I think the problem was that my desktop environment was doing something funky with the way it passed arguments to the mutt executable. After reading your e-mail I fixed it by telling Firefox to call a script for mailto: links, and the script is just:#!/bin/bash xfce4-terminal -e "mutt $@"
That's probably not arguments. Mutt probably can't run without a terminal. I bet the missing terminal emulator was the problem.
