I think the Figure you create may be not registered in the pylab framework, and indeed I think this is not a bug. The --pylab switch tries to obtain the active figure, but because there is no active pyplot-Figure, it gets None from get_active() in your traceback. Then it fails.
I think --pylab is only intended for pure pyplot usage, when you use the oo framework, be prepared to make it fail. Does this help?
