Comment 12 for bug 447886

I'm able to reproduce this also, the important pieces to make it happen are:
1. a saved wifi connection
2. you have to setup your gnome-keyring with a password, rather than leaving it blank
3. reboot the system

Workarounds are pretty simple and could probably be release noted if this can't be fixed for final image. Either no password can be provided for the keyring, and you will never be prompted for it. Or, if you do provide a password, you'll need to actually click the "lock icon" that comes up when the system boots to bring the password prompt to the foreground. However, it is correct that this is a fairly significant usability issue and many are likely to run into the problem.
