This might not be the exact root cause but this is what happened to me : I am in Maverick Beta on amd64.
I added a new language (Tamil - India) to my list of languages. I already have English(USA) and Hindi bolnagri for a long time. I clicked on the keyboard preferences applet and clicked on "Show current layout". Suddenly the gnome screen began to represent the gnome screen from early 2000s with flat backgrounds and got a notification of this error. I had to restart the X to fix the issue. Hope this helps ! -- dconf-service crashed with signal 5 in g_closure_invoke() https://bugs.launchpad.net/bugs/625757 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
