[Matplotlib-users] Problem with dashes and savefig in 0.72.1

1) Running the dash_control.py example I get the
following error message (the problem is present on
both linux and windows installations):

Traceback (most recent call last):
  File "/usr/lib/python2.3/lib-tk/Tkinter.py", line
1345, in __call__
    return self.func(*args)
  File

line 543, in _draw_dashed
    renderer.draw_lines(gc, xt, yt, self._transform)
TypeError: CXX: type error.


2) And when using savefig I get :

Traceback (most recent call last):

    savefig('dash_control')
  File
"/home/camp/s991416/lib/python/matplotlib/pylab.py",
