I think that this error raise in (draw-text* stream object (+ cursor-x width) when 'width' is nil (:WIDTHS #(NIL 9) in arguments). I don't know internals of Drei at all so I can't give you more details.
Indeed, I committed a patch to fix this. I wonder why it didn't happen more often, actually. Thanks for the bug report.
