I get a different error when I try this in a notebook (using matplotlib 1.5.x): ``` <matplotlib.image.AxesImage at 0xaba8910>Error in callback <function post_execute at 0x7eed0c8> (for post_execute):

Certainly fixes would be welcome here, though it might be somewhat involved -- and might possibly require upstream fixes in matplotlib (I'm really not sure).
