Yes this is a bug -- take the line in axes.Axes.set_ylabel that reads

        if fontdict is not None: self.title.update(fontdict)

and replace it with

        if fontdict is not None: label.update(fontdict)

(oops)

This is not too informative. Unfortunately, non-developer CVS lags
can be so long that "latest" can be any of many different versions.
Most helpful would be a revision number of the file you think is
involved in the bug
