So in displayOn:using:at:, positionWhenComposed is nil.

Looking at where this gets set, we see moveBy: , but this couldn't be it, 
because it gets set to the result of #+, which isn't likely to result in a 
nil.

The other place that this is set is in NewParagraph>>positionWhenComposed:.

So I'd put a conditional halt in that method to find out who is setting it to 
nil:

NewParagraph>>positionWhenComposed: pos
pos ifNil: [ self halt ].
positionWhenComposed _ pos.
