--- Comment #17 from fujiwara tfujiwar@redhat.com --- (In reply to comment #16)
If you rename $HOME/.cache/dconf/user , are you able to reproduce your problem with your current account? I'd need to know what was changed in your environment. I guess you won't reproduce your problem if you clean up all the dot files in $HOME.
Correction: $HOME/.config/dconf/user instead of $HOME/.cache/dconf/user
