Description of problem:
I'm unable to get the returned data from a GetAd call. 

Version-Release number of selected component (if applicable):
current svn head

How reproducible:
using the following python code:
    def gen_items(self, session, job):

        def completion(status, args):
            self.got_data = True

        ads = dict()
        model = self.app.model
        ret = job.GetAd(model.data, completion, ads)
        
        while not self.got_data:
            pass

The completion method gets called, but args is:
tuple: ('method', 'mrg2.lab.bos.redhat.com:5672', 3, 0, 'OK')


Steps to Reproduce:
1. Tested with latest svn cumin/mint code 
2. Connecting to broker at mrg2.lab.bos.redhat.com:5672
3. Select Grid tab
4. Select Main pool
5. Select Job with custom id 1.2
  
Actual results:
Job Ads are not returned to completion method

Expected results:
Job Ads should either be returned to completion method, or the dict that was passed to the GetAd function should be filled with the data.
