I thoroughly enjoy Org Contact for managing my contacts. One of
its features is the ability to enter +<tag-group> and have an
entire group of contacts added to the To: or Cc: . Unfortunately,
when global-helm-mode is enabled, it doesn't work; when `+<group>
TAB` is entered, an error occurs:
Lisp error: (wrong-type-argument sequencep 65)
I'm new enough to debugging elisp that the lengthy error trail
isn't very decipherable. Can anyone give me a hand on how to get
the TAB working with the contact-fill?
