From: David Bremner <bremner at debian.org>

Apparently as of GMime 2.4, you don't need to call
internet_address_list_destroy anymore, but you still need to call
g_object_unref (from the GMime Changelog).

On the medium performance corpus, valgrind shows "possibly lost"
leakage in "notmuch new" dropping from 7M to 300k.
