DBus Match Warning: match rule without a sender

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

  - Match rule without a sender criteria:
         - type='signal',interface='ca.desrt.dconf.Writer',path='/ca/desrt/dconf/Writer/custom',arg0path='/com/canonical/keyboard/maliit/'

In order to run the get-all-match.py script, you first need to install DBus from wily or from my PPA ( see below ). The script needs to be run with root permission, and the argument "--system" must be specified to attach to the system bus.

$ sudo ./get-all-match.py --system

Note, the same warning is seen on the session bus:

- Match rule without a sender criteria:
  - type='signal',interface='ca.desrt.dconf.Writer',path='/ca/desrt/dconf/Writer/user',arg0path='/com/canonical/keyboard/maliit/'

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