Subject: _notmuch_message_index_file: unref (free) address lists from gmime.
X-Git-Tag: 0.15_rc1~46
X-Git-Url: http://git.tremily.us/?a=commitdiff_plain;h=47693539a64b884cbd9bffc9c832162848ad98f2;p=notmuch.git

_notmuch_message_index_file: unref (free) address lists from gmime.

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.
