Description:Unfortunately I don't have much information about the nature of the crash, but if you need anything in addition to the backtrace please find me in IRC. It looks to be something to do with SIP realtime and the database connection...?

Backtrace is attached to this bug.

Try the following gdb commands:

(gdb) p rtp->rtcp
(gdb) p *(rtp->rtcp)

(gdb) p �p->rtcp
$1 = (struct ast_rtcp *) 0x0
(gdb) p *(rtp->rtcp)
(gdb) quit

Spoke with the person who is experiencing the crash, and he applied the patch yesterday and so far no crashes! He's going to follow up with me tomorrow to verify everything is good, but he'd have experienced a crash by now most likely.

At the end of a call, when we're reporting, RTCP may already be partially torn down, so check for NULL dereference
