Lots of warnings when restarting compiz

[Michael Heuberger]

Hello there

My compiz behaves weird, so I manually restarted it to get a list of issues. These are below.

Please have a look at the warnings / errors near the bottom and advise me what to do. Not sure if these are from a bug or from a misconfiguration on my machine.

Thanks!
Michael

There does not appear to be any bug here.

When you restart Compiz the previously running instance needs to be shut down gracefully and that fact propagated through the system. As the new process starts, some D-Bus service startups get delayed because the new instance has not yet acquired the bus name, and that fact is logged (it could possibly be the symptom of a problem under other circumstances). Similarly, during shutdown, the D-Bus name gets lost by the original program instance and that also gets logged.

I'm not surprised to see these messages when restarting Compiz from the command line, which is a fairly advanced thing to do. It would be more worrisome to see the warning messages appear in the session log.
