Terminal warning when opening a file in gedit
Solution 1:
The shell command:
export NO_AT_BRIDGE=1
prior to launch will squelch this annoying message.
Solution 2:
This seems to be a bug affecting Gnome software. See this link on launchpad: https://bugs.launchpad.net/ubuntu/+bug/1061554 I get the exact same on both of my Ubuntu 12.10 machines from the command prompt but gedit then works as intended. If you're having any difficulty editing the ddclient.conf file you could try nano which opens inside the terminal window, but otherwise I would ignore the warning message in this case.
