For Lummox JR or Tom, this appears to occur at line 4884 of smsg.cpp. It seems to be accessing a pointer that must have been freed but was not set to null. Looking through the code, I have a hard time figuring out how that could even happen. The object type in question is only deleted in a couple of places, and they seem pretty safe from this perspective.

I'm setting this to 'Unverified' since the cause isn't determined, and I'm not sure if there's much else we can do unless it happens again.
