This bug can be reproduced on GNU/Linux as well as W32. As Lennart's
instructions for reproducing it are somewhat scattered throughout the
thread, here are the steps again:

1) Load the patched tabkey2-patched.el (attached)
2) Create or visit an org-mode buffer with at least one heading and some
associated text under it, and ensure that the text is hidden. (example
attached).
3) M-x tabkey2-mode
4) Press F8 (tabkey2-first)


Emacs crashes inside next_element_from_display_vector in xdisp.c, with
it->dpvec == NULL.
