(also have mp for PyChecker, which failed miserably with the same message)

I must have done something *really* bad, I said to myself. Yet IMHO I
didn't (just paste'n'run):

class Weapon(Item):
def __init__(self, name, category, rarity=COMMON, weight,
damdie = (1,6), tdamdie=(1,4), material=None, effects = (),
todam_f = lambda: multirandrange(-1,2,3)):
super(Weapon, self).__init__( name, weight, damdie, tdamdie, rarity,
material, effects, todam_f=todam_f )
self.category = category

Apparently, removing todam_f fixes the FPE, as well as making the code
syntactically correct (moving rarity after weight.) Seems like something
got overlooked in the parser?

Almost forgot: Python 2.3/win98
