Hello,
it seems that either callid parameter was not provided or couldn't be
read from the mi command? Have you got any error message in syslog
before the crash?
I pushed a patch that does a safety check in order to be sure that
callid parameter has a value. You have to take the latest version of the
branch.
Cheers,
Daniel
