[O] regression in list/heading toggling?

[Eric Abrahamsen]

Hi all,

I've found what seems to be a bug in org-ctrl-c-star, toggling a
numbered list item to a proper heading. ECM is simply emacs -Q, make an
org buffer, put in the text:

1.

cursor on the number, then "C-c *". Text is removed, the window jumps,
and you get "(wrong-type-argument arrayp nil)".

I have a full traceback I can send to the list if necessary, but my
guess is it will be fairly reproduceable!

Thanks,
Eric
