Very sorry, but there was a bug occurring where the should_arena_attack 
was getting called with null pointers for targets for the pet to attack. 
I've made a safeguard that should prevent this problem exit first thing 
upon the pet, it's owner, or it's target being null values. I haven't 
been able to recreate the crash conditions that happened on metalforge 
with this bug on my local server, but I'm pretty sure this should fix 
it. I've committed this fix to CVS and I think it would be good if 
metalforge was updated again. Sorry for giving you this much work 
updating metalforge.

    Thanks,
