That's great Havoc. The earlier error handling (shown in the  commandline)
may not be shown at all for applets etc.

One more thing  we may not have a gtk window always for
the dialog box , so we can have  something like

dialog = gtk_message_dialog_new (NULL,

GTK_DIALOG_MODAL,
                                                                 ........ );
