I cannot reproduce this with the Org file you've sent, if I perform
the steps above starting from "emacs -Q".

Please do, I need a reproducible recipe starting from "emacs -Q" in
order to debug this.

> ../../emacs-24.3.91/src/xdisp.c:6066: Emacs fatal error: assertion failed: (BUFFERP (it->object) && IT_CHARPOS (*it) == it->bidi_it.charpos && IT_BYTEPOS (*it) == it->bidi_it.bytepos) || (STRINGP (it->object) && IT_STRING_CHARPOS (*it) == it->bidi_it.charpos && IT_STRING_BYTEPOS (*it) == it->bidi_it.bytepos) || (CONSP (it->object) && it->method == GET_FROM_STRETCH)

This is an assertion violation, not a crash.  Some assumption in the
code turned out to be false, but it is not possible to know which one,
and whether it's just a wrong assumption or a real problem.

So a reproducible recipe is required, I hope you can find it.

Thanks.
