[squeak-dev] [BUG]UndefinedObject(Object)>>doesNotUnderstand:

here insert explanation of what you were doing, suspect changes you've
made and so forth.

I had opened a croqet window in a virgin image, wandered around a little
bit, left the room, and got this error. I thought it had locked but it
was merely being incredibly slow. =\
