Without context, it would be hard to say.  What was the exception message?
 I bet it was a NoneType object being returned by get_figure(), which would
mean that the Axes object was created without a figure, which is rarely
done.

Also, it looks like the code was trying to manage the hierarchy of objects
itself (maybe the code was trying to detach an axes from one figure and
transfer to another?  Lots of bookkeeping code like this is not needed, but
you may still have other issues lurking.
