Cannot debug nose tests using jython

PyCharm Community Edition 3.1.1
   Build #PC-133.881, built on February 14th, 2014
  
(En passant - it would be really helpful if the About Box didn't disappear as soon as I started typing into the browser! And it would be really nice if I could copy that version info from about box!!)

Running on Ubuntu 12.04

I have Python 2.7.5 and Jython 2.5.6 installed and nosetests installed into each

I create a simple script (called fred.py)
    def hello():
        raise ValueError('world')

I create a simple test script (called test/test_fred.py)
    from nose.tools import raises
    import fred
    @raises(ValueError)
    def test_hello():
        fred.hello()

No problems with any of these scenarios:
    1. run the script with python
    2. debug the script with python
    3. test the script with python
    4. debug the test with python
    5. run the script with jython
    6. debug the script with jython
    7. test the script with jython

This scenario causes a problem:
    8. debug the test with jython

Problem looks like this in the test output window:

This is shown when debugging the test under python (works fine):

And this is shown when debugging the main script under jython (also works fine)

===
En passant - that message about "sys._current_frames is not supported in Python 2.4" seems redundant:

$ jython –version
Jython 2.5.4rc1
