    return Instances(javabridge.call(self.jobject, "getDataSet", "()Lweka/core/Instances;"))
  File "/usr/local/lib/python2.7/dist-packages/weka/core/dataset.py", line 48, in __init__
    self.__set_instance = javabridge.make_call(self.jobject, "set", "(ILweka/core/Instance;)Lweka/core/Instance;")

The issue is with python-weka-wrapper. The bug has not been fixed in the stable release, but it has been fixed in the current build, so you can directly build from source.

This issue was not present in older stable versions.
