If you are calling queue_draw() in the layout thread, you should note that GTK+ is not thread safe unless you are also using a unix-like environment and lock and unlock the gdk global lock (the global lock cannot be used with windows). libsigc++ employs no locking and so is also not thread safe unless you employ external synchronisation (and because of the design, sigc::trackable is extremely difficult to use safely).
