It seems as though the agent device state subscription is NULL, and that
causes a problem when we try to unsubscribe. I have made a patch which
simply tests that the pointer is non-NULL prior to calling
ast_event_unsubscribe. Please test 13476.patch to see if it fixes the
problem. I created the patch against the the latest 1.6.0 subversion
checkout, but the patch should also apply cleanly to the 1.6.0-rc6 tag as
well.
