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.
