    mime-actions: don't use g_object_set to set dialog text
    
    Currently, the text for unhandled type message dialogs is set by
    setting the associated GObject properties. That is unnecessary and
    results in hardcoded property names.
    
    The fix is to use GtkMessageDialog functions.
