Like I thought: a completely different bug than 7616.  Should be fixed
now (revision 103905).

Of course, plenty of funny behavior is still there; e.g., try up-arrow
or even right-arrow (feel free to submit a separate bug report with
all the symptoms), but at least it no longer crashes that easily.  I
need to take a good look at the bidi operations in the presence of
invisible text, sigh.
