Branch: im.pidgin.pidgin

Modified files:
        libpurple/protocols/bonjour/bonjour_ft.c

ChangeLog: 

Fix some confusion between iq ids and sids. This allows me to send files to Gajim (as long as Gajim has initiated the connection to me - there seems to a bug there where it will try to make a new connection if I've initiated the connection). Also fix a null ptr deref crash.
