DBus Match Warning: match rule without a sender

If get-all-match.py ( see attached ) is run on the session bus of the latest rc-proposed touch image, the following warning is output for evolution-source-registry:

   - Match rule without a sender criteria:
         - type='signal',interface='com.google.code.AccountsSSO.Accounts',member='AccountChanged'

In order to run the get-all-match.py script, you first need to install DBus from wily or from my PPA ( see below ).

I'm reporting this after running the tool on krillin, rc-proposed/bq-aquaris.en, #196.
