Re: [O] Bug: check that org-element--cache-sync-keys is non-nil before clrhash [8.3.4 (8.3.4-42-gae73c7-elpa @ /home/mah/.emacs.d/elpa/org-20160425/)]

I removed [gnus-alias-use-identity](https://www.emacswiki.org/emacs/GnusAlias) 
and the problem went away.  I'm guessing it is because some sort of race 
condition when I reply to a message.  I would gues that org-mode is invoked 
when the signature files are inserted into the message.
