Steps to reproduce:

1. Start Sound Juicer.
2. Insert a CD, one known not to have MusicBrainz data for it available.
3. Eject CD.
4. Insert same CD, or another CD with no MusicBrainz data for it.

What happens:
A dialog pops up saying ”Cannot access CD: Error while getting peer-to-peer dbus connection: The name :1.395 was not provided by any .service files” (the number varies). Data from CD TOC isn’t filled into Sound Juicer’s main interface.

What I expect to happen:
No dialogs to pop up, data from CD TOC read into Sound Juicer’s main interface just as it was after step #2.

Workaround:
After step #4, shut down Sound Juicer and then start it again. You’ll have one working read, and again failure on successive reads.

Other info:
Bug #977335 is similar, but without the MusicBrainz connection. I’m unable to reproduce #977335 with CDs that do have MusicBrainz data available for them.
