    Print error from D-Bus in case of failure in oobs_session_get_platform()
    
    This method call is particularly critical since it's where all visible failures loading the GUI happen. Printing a warning allows debugging the "Unexpected error" we report in a dialog. Also fix a printf warning in the other D-Bus error report.
