I find this very difficult to believe - especially considering that nobody else 
has reported this problem.

Nonetheless, because you provided definitive evidence of at least one buggy 
server, I've now installed a new version (2013.04.04) of the code that should 
avoid crashing this server.  The proxy code will now always sends "OPTIONS" - 
rather than "GET_PARAMETER" - as the 'liveness check' command, unless the 
server explicitly indicated (by a "Session:" header "timeout" parameter in the 
"SETUP" response) that it wants to receive periodic in-session "GET_PARAMETER" 
commands instead.  (Some servers have another bug whereby they don't use RTCP 
"RR" packets - from the client (or proxy) - to indicate client (or proxy) 
liveness.)

Yes, but I still find it strange that nobody else has reported this.  (It would 
be nice to get independent confirmation of this from a professional user, and 
also have this bug reported to the camera manufacturer(s)!)
