I'm a big fan of getting rid of all these stupid NULL checks in
the rpc_parse code.  If a parameter is NULL then it hasn't been
passed in by the programmer and smbd should segfault.  This will
pull up the error much faster than tracking back up many stack
frames to to find out why a particular call has failed.

Woohoo - a rant!  I don't do this very often... (-:
