"yelp INFO:foo" produces forkbomb

[Ryan Finnie]

Running "yelp INFO:foo" (or INFO:anything) opens a blank help window which seemingly cannot be closed, moved, minimized, etc. No other input is possible. Switching to the console reveals two yelp processes, one which remains, and which constantly launches children in series, all of which immediately die. "killall yelp" from the console allows me to get access to the desktop again.
