I installed Xubuntu 14.04 with the most recent libgtk-3-dev library. Then I recompiled all my C programs. Now all these programs output a warning which was not there before, when I had these programs running under Xubuntu 13.1 with the old libgtk-3-dev. The warning is
** (program.x:2430): WARNING **: Couldn't connect to accessibility bus: Failed to connect to socket /tmp/dbus-DpOEDwyIbh: Connection refused
How can one suppress this message?
