Description Philipp Hahn

While USS is running, firefox tries to start dbus which fails and constantly spams the log with the following messages:
> (firefox:555): GConf-WARNING **: Client failed to connect to the D-BUS daemon:
> /usr/bin/dbus-lauch terminated abnormally without any error message
> process 555: D-Bus library appreas to be incorrectly set up; filed to read machine uuid: Failed to open "/etc/machine-id": Datei oder Verzeichnis nicht gefunden

See <http://www.freedesktop.org/software/systemd/man/machine-id.html>

apt-get install dbus-x11
[ -s /etc/machine-id ] || tr -d - </proc/sys/kernel/random/uuid >/etc/machine-id


I don't know what functionality of firefox is missing without dbus, but the log spamming should be removed at least.

It was also reported by a tester.

If firefox is started from the command line, it continuously outputs:
> (firefox:4022): GConf-WARNING **: Client failed to connect to the D-BUS daemon:
> /usr/bin/dbus-launch terminated abnormally without any error message
> process 4022: D-Bus library appears to be incorrectly set up; failed to read machine uuid: Failed to open "/etc/machine-id": Datei oder Verzeichnis nicht gefunden
> See the manual page for dbus-uuidgen to correct this issue.
