gnome-libs isn't threadsafe at all (GTK+ isn't really either, but it
does provide the global lock manipulated with
gdk_threads_enter()/gdk_threads_leave(); gnome-libs doesn't use this
lock). Anyway basically only one thread can use gnome-libs as far as I
know.

The easiest workaround is probably to queue an idle handler that shows
the URL, since you can queue an idle handler from any thread. Have the
idle handler return FALSE so that it runs only one time.
