Summary:                    Redirecting Local channels to Meetme causes a crash
when executing "core show channels"
Description: 
We have an Agent channel in a conversation with a local channel.  Using the
Redirect command from the manager, we take the local channel and send it to
a meetme app.  We then initate 2 calls with the Originate command which
adds the agent and the 3rd party to the conference.  We don't use the
ExtraChannel parameter of the Redirect command as we need to set different
options for the local channel.

Once the agent wishes to drop out of the call, they hit '*' to disconnect.
 They don't hear any hold music and the agent channel is no longer able to
receive calls.  Having a call sent to the agent causes asterisk to deadlock
almost completely.

This is reproducable in both versions 1.2.10 and trunk, however the debug
log is from trunk with DEBUG_CHANNEL_LOCKS, DEBUG_THREADS, DETECT_DEADLOCKS
and DONT_OPTIMIZE being set.

BigJimmy,
  Is the uploaded 'core show locks' output the only reason you believe you
channels are deadlocked ?  If not, what other side effects of a deadlock
are you experiencing since the crashes were fixed?
   I'm duplicating the steps you gave to cause the deadlock via AMI and
I'm not seeing your problem.  Would it be possible for you to provide a
script that I can use to definitely reproduce your problem?  You don't have
to provide the script here if you want to get it to me another way.
