If you can provide an example that exhibits this behavior, it
would be much appreciated. If that isn't feasible, a stack track
would also be useful.

Any assertion failure is definitely a bug - inserting without
freezing the widget is supposed to work, although it will
be slower than freezing than thawing. (If you insert more
than 1024 characters at a time, it automatically freezes and
then thaws to speed things up anyways.)
