Description Paul Menzel 2012-10-05 14:08:51 UTC

Starting self-built Rhythmbox 2.98 under Debian Sid/unstable under GNOME 3 and Tracker miners running, the following message is printed to the terminal.

    GLib-GIO-CRITICAL **: g_dbus_connection_register_object: assertion `object_path != NULL && g_variant_is_object_path (object_path)' failed

Here is the backtrace. If the cdparanoia debugging symbols are needed I am happy to recreate the trace.

Thanks as always for the quick solution [1]. For the next commits could you please also paste the errors into the commit message. That would be much appreciated for people looking through the commit log and not knowing what extent the fixed error had. I know you paste the Bugzilla bug URL, but it is not made a clickable link in cgit [1] and never will be one for people using plain `git log`.

Thanks again!
