remiq: what is the sequence you use to crash?
Is it 2 users pickup the same ringing extension?

Using the method of 2 users pickup same call, with Asterisk
SVN-branch-1.8-r319654M without reviewboard 1221 download I was able to get
a Playback on a ZOMBIE channel!!!!!

After applying review board patch, always seemed good.
