I think the bug is in the definition of ns-unput-working-text (or in
the way ns-unput-working-text and ns-unput-working-text (both events
and functions) interact).

Not sure why ns-working-overlay was nil in your case, so either
ns-unput-working-text should be careful to handle the case where that
variable is nil, or some other code should make sure that it can't be
nil when we reach ns-unput-working-text.
