Comment(by erikos):

 Asaf, yes the traceback above suggests that the world object contains non
 serializable parts. Maybe looking at the pickle code in elements helps.

 {{{
 def pickle_save(self, fn, additional_vars={}):^M
         import cPickle as pickle^M
         self.add.remove_mouseJoint()^M
     ^M
         if not additional_vars and hasattr(self, '_pickle_vars'):^M
             additional_vars=dict((var, getattr(self, var)) for var in
 self._pickle_vars)^M
 ^M
         save_values = [self.world, box2d.pickle_fix(self.world,
 additional_vars, 'save')]^M
 ^M
         try:^M
             pickle.dump(save_values, open(fn, 'wb'))^M
         except Exception, s:^M
             print 'Pickling failed: ', s^M
             return^M
 ^M
         print 'Saved to %s' % fn
 }}}
