failure to set or reset environment on sudo calls is an admin problem.
I did not call cfg-update using sudo. As you can see below meld is executed as root.
the way you get root access counts, if you do sudo -s or su, you have to fix your environment before starting random apps. In this case, you have to unset DBUS_SESSION_BUS_ADDRESS.
I think instead of "su" you can use "su -" if you want this to work, that's what I'm always using without having any problems, as it makes it so as if you would have logged in as root

Why can't the package be installed in a way that typing "su -" (which is tideous imo) is not required.
That's up to you to know the difference between "su -", "su" and "sudo". meld only does what it's told to do and it'd be a hell of a mess if every app had to have special code to figure out what do when root or not, or if the environment is different. "su -" resets all your user environment, that's all you should be using anyway. I'm sure sudo has a similar option as well. Thanks
*** Bug 289261 has been marked as a duplicate of this bug. ***
Obviously I haven't been paying attention, I have been using Linux exclusively since '97 and Gentoo in particular since '02/'03, yet this is the first time I have even heard of 'su -'. Gotta love it, you learn something new every day when you use Linux :-)
Since today I have the same error. I can't start meld as root after doing 'su -'. What has changed? If I start '/usr/libexec/gconfd-2' as root manually in a second window, then I also can run meld and other gnome applications (which interact with gconfd?).
Please reopen this bug.
I have to correct myself. This procedure to start manually gconfd-2 works only at one computer. At the second computer starting meld kills a running gconfd-2. Any help appreciated.
reopened on request
Still a further correction, it seems me, that meld is not killing a running gconfd, but the gconfd is dying at the first computer after some minutes and at the second computer after some seconds.
Isn't gconf supposed to quite after the last application using it stopped ? Could you paste the output of meld when run as you use it ?

So your gconf is actually crashing in the first case, the second being the normal exit I described in comment #14. Could you start gconfd-2 in gdb as your "rose" user, try to run meld as root and attach a backtrace when it gets a sigbus ? Also please print the output of: # env |egrep DBUS_SESSION_BUS_ADDRESS in your root environment.
