Summary:                    [patch] segfault in app_chanspy.cpp
Description: 
Due to some kind of race condition that I wasn't able to identify exactly
(most likely a channel disconnected while trying to attach to it for
monitoring), ast_bridged_channel(spyee) (called from channel_spy) returns
null pointer which start_spying tries to dereference without checking.
Backtrace and patch are attached.
