dmesg

Description of problem:
After booting with live-CD in Gnome 3.2 the system shows: Oh no! It goes something wrong!
But when I logout I can afterwards login and all works fine.
With older nightly builds and F16alpha and beta-versions where was the "Oh no! Something goes wrong" more present. In these older version the "Oh no! Something goes wrong!"-message appears also after booting the livecd but the logout and login also calls the message "Oh no! ..." Also the fallbackmode doesn't worked.
Now I can do the workaround to logout and login and all seems to work fine. (No fallback mode).
The annoying is. I can't do when this message appears. because this message is topmost. I can go in the overviewmode with Superkey (Windows-Key) and all looks fine and I can open programs, but when I select a program it lays unaccessable under the "Oh no! ..." message. -> With 2 Monitors I can go to the overview-mode and drag a opened programmwindow to the second monitor. Now I can work on the second monitor, while the "Oh no! ..."-message is only on the first monitor.
