This is a known bug which means that the monster initialization part of
rogue has bombed.  Basically, when a monster is encountered (ie at the end
of the corridor), the program looks for the monster in its monster table and 
finds that is doesnt exist.  Such games usually have other problems and should
be quitted early.  Other symptoms of this problem include monsters in reverse
video, or items (scrolls and potions) which when picked up are called
'Something Bizzare'.
