I've not looked at the code, i'm just speculating here....

I've seen cases where a unicast subnet route is rejected if there is
no route which leads to the gateway. It could be your multicast route
is being rejected for the same reason.

An idea.... 

Grab a live CD of FreeBSD. http://livecd.sourceforge.net/ Run strace,
or what ever the BSD equivalent is, on adding the route. You can then
see what parameters it passes.
