bug#33613: 25.2; mail-header-parse-address: scan-error "Unbalanced parenthesis" 7 32

[micah anderson]

Hello,

I was trying to send an encrypted email while in notmuch, to a user
whose openpgp key had expired. When I tried to send the mail, I would
get the following in the mini-buffer:

mail-header-parse-address: scan-error "Unbalanced parenthesis" 7 32

I did M-x toggle-debug-on-error and tried again, and I see this:

Debugger entered--Lisp error: (scan-error "Unbalanced parentheses" 7 32)
  scan-sexps(7 1)
  forward-sexp(1)

  #[(name) "\306       \n#\211G\211\307U\203&

Once I refreshed this user's key, I was able to send the message without
error. The user has some UIDs on their key that have a comment in them
with ascii ducks:

(3)  dre ebs (>O_/) <dre@bar.org>
(4)  dre ebs (\_O<) <dre@foo.net>

They have been revoked now that I refreshed, so I guess it did not
consider these keys because of that, but before it was considering them
and was choking on the ducks, a sexp injection?

Thanks!
micah
