The problem is caused by the characters U+25B2 BLACK UP-POINTING
TRIANGLE and U+25BC BLACK DOWN-POINTING TRIANGLE used in
`tabulated-list-init-header' to mark the sorting order.

What is the value of it->what in this frame (frame #1)? If it's
IT_GLYPHLESS, then I have just fixed that on the trunk (the problem
was that xassert didn't allow IT_GLYPHLESS, while the code below
clearly handles it). If it->what is something else, please reopen the
bug.
(Ironically, I found and fixed just a few days ago this same bug on my
local branch where I work on bidi.)

I thought Chong installed a change that was supposed to DTRT with
these characters on a TTY?
