[Twisted-Python] why insecureJelly

I want to send objects accross the network and all I get is insecure Jelly.
My application looks like this:
-folder structure:

in common is the declaration of the object which should be send:

from dispyte.baseclasses import Task #thats the abstract baseclass
from twisted.spread import pb

class SimpleTask(Task.Task, pb.Copyable, pb.RemoteCopy):
	def __init__(self):

pb.setUnjellyableForClass(SimpleTask, SimpleTask)

these objects are created by a instance of a class located in GACrysVUn:

from dispyte.baseclasses import Producer
from dispyte.common import SimpleTask

class GACrysVUnProducer(Producer.Producer):

	def foo():  #just as examlpe of the structure
		task = SimpleTask.SimpleTask()

the task-object is given to another class instance lockated in common:
here the task object is send:

	factory = pb.PBClientFactory()
        reactor.connectTCP(parameters[0], parameters[1], factory)
	def0 = factory.getRootObject()
        def2 = self.root.callRemote("fitness", task, self.taskDescription, 
        def2.addErrback(self.errback, task, self)

the server looks like:

from twisted.spread import pb
from twisted.internet import reactor,threads
from dispyte.common import SimpleTask
from dispyte.common import ScriptedTaskDescription
import sys
class ServerObject(pb.Root):


    def remote_fitness(self, task, taskDescription, serverID):
        calls calc in seperate thread and return a deferred
        self.ID = serverID
        print "ServerObject::remote_fitness ..."
        return threads.deferToThread(self.calc,task,serverID, taskDescription)


if __name__ == '__main__':
    factory = pb.PBServerFactory(ServerObject(sys.argv[1]))
    reactor.listenTCP(eval(sys.argv[1]), factory)

I can't figure out, why insecureJelly is raised here. Can anyone help me?
And: Is there a possibility to turn off this feature, so that a server takes 
objects no matter what class?

Thanks in advance.
