"Oh no! Something has gone wrong" first login after boot: where is it being logged?
 

I have recently upgraded my Fedora 15 to 17. I use Gnome. Now, after a reboot, the first time I try to log in, it always comes up with the rather uninformative (ie as useless as Windoze messages were, last time I looked many years ago) "Oh, no! Something has gone wrong" message. I click on 'Log out' and try again. The second attempt works fine.

I have tried to discover where the reason for this failed login is being logged, so I can see what has caused the "Oh, no" message, but none of the logs under /var/log seems to contain any relevant information. Obviously, an error has triggered the message, but what is it and where is it being logged?

I have asked this question at Fedora Forum, but no replies have helped. I have also logged it as a bug.

Any help would be appreciated.

Here's a thread from the fedoraproject.org forum that discusses that very issue:
http://ask.fedoraproject.org/questio...fix-filesystem

Unfortunately, the situation covered by that thread is different from mine. I do not get any additional messages or notifications. I only see the "Oh, no" message when I log in to a fully booted and happily running system. My start-up applications - those that were open when I last shut down - are all running and I can see them in the view obtained by moving the cursor to the top-left corner of the screen, or by pressing the Windows key on the keyboard. The only thing not running is what I would call my active screen - the one where the "Oh, no" message is appearing. When I log out and log in again, everything is sweetness and light. I would love to be able to discover what is triggering the "Oh, no" message, but my logs don't tell me anything. Where would this be logged - any idea?
