Summary:                    Joining a MeetMe conference and hanging up shortly
after results in SIGSEGV
Description: 
In my 1.6.0-rc6 installation, if a user joins a conference and then hangs
up shortly afterward (i.e. during the only-person announcement or during or
shortly after the join chime), Asterisk takes a SIGSEGV to the head. 
Sometimes I can reproduce this on the first try, sometimes it takes two or
three consecutive quick join-hangup to reproduce the issue.  It seems to
occur regardless of whether I enter MeetMe with no arguments or with a
conference ID and PIN specified.

I'm running almost exclusively SIP on this system, haven't tried to
reproduce issue with any other technologies.  Timing source is a TDM410P,
crash happens with dahdi-linux 2.0.0rc4 and trunk.

It would appear that there is some configuration data 'leaking' from the
last channel you have configured in chan_dahdi.conf into the pseudo channel
used by app_meetme; please try the attached patch which attempts to resolve
this situation.
