UI manager problem, more concise

[Nick Watts <fatalglory gmail com>]

Umm, lets see. I have a whole bunch of UImanager code, but none of it causes 
an error until I get to this:

if (!gtk_ui_manager_add_ui_from_string (ui, ui_info, -1, &error))
{
g_message ("building menus failed: %s", error->message);
g_error_free (error);
}

The weird thing is that although I get a bunch of Gtk-CRITICAL errors in the 
program, the GError error is not set and the message is not 
displayed. Is there any problem with using the uimanager functions inside 
the main() or gtk_main() functions of your program?
