Is is possible that this mail's body is ctype 'text/html' and you haven't set up
your mailcap for html (as in FAQ #5 or issue #622)?

BTW: why did you not notice this earlier in the 'testing' branch? :P

I cannot think of anything else atm, sorry. Maybe Justus has an Idea?
Could you open an issue about this with some more details about the mail and your setup?
