[BUG] fill-paragraph in orgstruct mode blows up

[BUG] fill-paragraph in orgstruct mode blows up

[Nick Dokos]

I use orgstruct mode when composing email and fill-paragraph blew up
with the following backtrace when I tried to fill a paragraph after a
drawer, as described in the last paragraph of this email.

:SETUP:
# Local variables:
# eval: (org-update-all-dblocks) -*-
# End:
:END:

This is a dummy paragraph after the drawer. Put cursor here and call fill-paragraph
after enabling orgstruct-mode. You should get the error below.

Org-mode version 7.5 (release_7.5.86.g6daa.dirty)
