Okay, I did more testing.  Definitely the issue is overlapping DESCRIBE,
SETUP, SETUP, PLAY, TEARDOWN sequences.  And for me, the problem was
exacerbated by the fact that my client would connect to the server _twice_
(once to fetch media types, then a TEARDOWN, and again to start pulling
media).  I changed it so my code connects a single time and I can no longer
reproduce the crash.

So I think there is a bug in there somewhere, and it definitely involves
overlapped sequences like that.  I did try to isolate it with mediaServer
and openRTSP, but...haven't had a lot of luck.  I'll let you know if I find
out anything else.
