One interesting piece of information in the latest backtrace which was not
present in the first is that the ast_channel structure on which the lock is
attempted is NULL. This would point to a different race condition, one
where the channel is hung up but we still think the channel is running an
application. There's a really simple solution to this problem, check to see
if the channel is NULL before attempting to lock it. The problem  is that
I'm not sure yet if this is a symptom of a deeper problem or not. I will
look more closely and try to get a patch uploaded as soon as I can.
