Aha.  And what is that red block the size of a cursor (but evidently
not a cursor) at the end of the line which causes the abort?  Where
did that come from -- a buffer position with a special face?

I'm past the line where debugging by asking questions stops being
efficient.  A reproducible test case would help tremendously, assuming
it is feasible for you to come up with one.  Or maybe I will see the
light and either find the problem by code inspection or find some
clever way to catch it and yet simple enough to ask you to do it.
