I confirm this bug too, i get the white screen of death when i logout from a second account while leaving the first one logged out. I can login back to the first account by blindly typing the password of the account.
People here have suggested pressing Ctrl+Alt+Backspace to restart the GUI Shell, but the alternative i suggest is pressing ALT+S at the white screen which will reload only the Login screen and thus you will not lose any work from the account which is locked.
