We had a crash with a similar traceback, except that it went deeper, and
actually crashed in ast_frdup.  Unfortunately we'd accidentally stripped
the main executable when creating an RPM, and also it wasn't reproducible. 
We were assuming a delayed result of memory corruption, as our AMI
application was complaining about receiving gibberish at about the same
time.

In our case, the agent was an AgentLogin one and the actual agent was a
local channel connected from a SIP channel.  We believe the audio file was
the beep file.
