    applet: don't crash in nag_dialog_response_cb (rh #619775)
    
    nag_dialog_response_cb can be called more times, so we can't free
    info structure there yet.
    The bug is a regression caused by:
    "nm-applet: remember "Don't warn me again" checkbox value about missing certificate (rh #610084)"
