Matt Jordan commented on ASTERISK-20574:
----------------------------------------

I've removed your backtrace from the comments and attached it as a separate file (ASTERISK-20574-backtrace.txt).  Please do not paste large blobs of anything (much less backtraces) in a comment - attach them as separate files.

Despite the fact that a chan_motif channel was being used at the time, this appears to be a crash occurring in MeetMe as it attempts to access the channel after it has been ref counted out.  This is more likely to be a general problem with MeetMe than a problem with the chan_motif channel driver.  Keep in mind that MeetMe in Asterisk 11 is an extended support module and development support for it comes primarily from the Asterisk community.
