I think you need to call queue_draw() on the StatusBar widget, and then 
if you want to force a repaint, you need to do:

while(Gtk::Main::events_pending()) Gtk::Main::iteration();

The important thing here, is that the GUI thread needs to do this, or 
else everything gets messed up. A solution is to let the other threads 
emit a signal when something needs repainting, and let the GUI thread 
listen on that signal, and call the above while loop. A normal signal 
won't work across threads, so I use a Glib::Dispatcher, which let you 
pipe signals across threads.

Hope this helps.
