This pair of patches should be safe and clean to apply.  When they're
applied, though, the gmime 3.0 series no longer passes the test suite
due to these failures:

----------

 PASS   Multiple recipients

I think this is due to "notmuch reply" crashing on those first two tests
with a segmentation fault.

i think this implicates the reply-to munging code, which i don't
understand, but would welcome help on debugging.
