I propose to change the line in ibrowse.display(self)

        if hasattr(curses, "resize_term"):

to

        if hasattr(curses, "resize_term") and getattr(signal, 'SIGWINCH', None):

Fix committed to 0.10.1 and trunk (though in trunk ipipe is currently disabled until it gets updated to current apis).
