[Orgmode] paralyzing bug: orgmode typeface gibberish

[Michael Gilbert]

Hi —

My setup: Aquamacs 2.1 (Emacs 23), Orgmode 7.01h. This came about a few minutes 
ago, after a routine reboot. 

When set to org-mode, my buffers now display some gibberish typeface that I 
don't recognize (forgive the attachment):

Same buffer, when flipped to text-mode:

I am totally lost as to how to approach this. And, after a year of entwining 
myself deeper and deeper into org-mode, I am dead in the water. Maybe I will go 
take a walk. I understand there is an Outside World to visit.

Anyway, any thoughts?
