An inconsistency in the definition of save_figure between different backends is
causing this problem.
The GTK backends use
def save_figure(self, button):
but the tkagg, qt, qt4, and macosx backends use
def save_figure(self):
so without the second argument. The line that is causing the error is
self.canvas.toolbar.save_figure(self.canvas.toolbar)
in backend_bases.py. This assumes that the save_figure method is defined as in
the GTK backends.
As far as I can tell, the GTK backend has the second argument because that is
what pygtk passes when save_figure is called as a callback. The second argument
is not actually used inside the method.
So I would suggest the following:
In backend_bases.py, change the offending line to
self.canvas.toolbar.save_figure()
and the backend_gtk, change the definition of the save_figure method to
def save_figure(self, button-None):
Any objections, anybody?
