Looks like a gnome-panel bug, since it's the program using CPU. But if you're not able to reproduce it, we cannot do anything but close the bug! What happens if you retry the same operation, e.g. from a separate user accout?
For the record, when trying to debug, you should move configuration directories instead of removing them, since we would need them to find the problem. For the sound control, add the indicator applet to the panel. -- gnome-panel did not start properly after I moved it https://bugs.launchpad.net/bugs/599462 You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to gnome-panel in ubuntu. -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
