This is a bug.  I removed the xclip "feature" from the line class
because noone was using it and it wasn't helping performance (which
was it's original aim).  But it appears there is a lingering reference
in the axes.py code for users using the "classic" toolbar.  Search for
"set_xclip" n the axes.py code an comment out lines like

        for line in self.lines:
            line.set_xclip(xmin, xmax)

Or else set your matplotlib rc setting to

toolbar      : toolbar2   # None | classic | toolbar2

Hope this helps,
