For the curious:

Looks like a chan_sip.c bug though its actually crashing in do_monitor
of mail/utils.c .

In the console I get a lot of:

[Nov 10 17:36:35] WARNING[24788]: io.c:234 ast_io_remove: Asked to remove NULL?

.. and ..

[Nov 10 17:36:48] ERROR[12514]: /usr/src/asterisk-1.4/include/asterisk/lock.h:336 __ast_pthread_mutex_unlock: chan_sip.c line 13714 (handle_request_refer): mutex '&current.chan2->lock' freed more times than we've locked!

While testing I notice that the actual transfers get slower and slower
before the crash. By slower I mean you hit "transfer" and the call is
gone from the one phone but the destination doesn't ring immediately.
There is a second or so delay or it just segfaults.

It should also be noted that while blind xfers trigger crashes fairly
quickly, Asterisk is also crashing at other seemingly random times.
