In my Emacs.org configure file, org looses track of children and
subheadings. Hitting tab does nothing. If I switch to fundamental on

the buffer, everything under the bullet seems to be gone. However on a save, all data that was originally in the file shows up again. Sometimes when I reload
(i.e. kill and and reopen, not revert) the buffer I get the following warning:

Warning (org-element-cache): org-element--cache: Org parser error in Emacs.org::361. Resetting.
The error was: (error "Invalid search bound (wrong side of point)")
Backtrace:
" backtrace-to-string(nil)
org-element-at-point()
org-back-to-heading(t)
org-fold-heading(nil)
org-fold-show-set-visibility(tree)
org-cycle-internal-local()

funcall-interactively(org-cycle nil)

"

I'm running emacs and org under Guix (gnu+nongnu).
