When trying to run meld on Ubuntu Desktop 13.04, I get the following error:
$ meld (meld:1509): GConf-WARNING **: Client failed to connect to the D-BUS daemon: Failed to connect to socket /tmp/dbus-EQeHnPP7h5: Connection refused Traceback (most recent call last): ... glib.GError: No D-BUS daemon running
I am running as a non-root user, with a X11 forwarding through PuTTY/SSH to Xming.
