[O] org-contacts and column mode

[George McNinch]

If I have a buffer visiting one of my org-contacts files, say contacts.org,

and if I have turned on "column mode" in the buffer visiting
contacts.org via org-columns ("C-x C-x C-c")

then, when trying to tab-complete in a *Message* buffer

To: George <tab>

in the event that George identifies an entry in the file contacts.org, I
get an error report in the minibuffer:

   Text is read-only: "Type `e' to edit property"

If I quit column mode in the appropriate buffer, then tab-completion
resumes working correctly.
