Comment 1 for bug 621377

This problem means that two programs that use this service at the same time won't be able to tell who the signal was sent for.

In order to avoid this we need to add the app_name as an argument to all these signals so the users of this service can tell the signals apart.

Right now this service is used by Ubuntu One and the Software Center, so it may make sense to do this change before more programs start using it.
