Have your menu item handler install an idle action that starts the  
dialog box.  That is:

1  user activates menu item
2  menu handler is called
3  menu handler does Glib::Idle->add (\&do_the_thing);
4  menu handler finishes, menu disappears
5  control returns to main loop
6  main loop sees that there is a pending idle action
7  do_the_thing() fires
8  do_the_thing() launches your dialog box

In essence, it's just a layer of indirection to defer running the  
dialog box until "sometime later".
