Sorry, I have been travelling. I admit that I am a little confused as to what your question is: I do not maintain sklearn's KernelPCA implementation, nor is this the appropriate repository to report such an issue. You should perhaps try filing an issue with sklearn, but you may have better luck with the gitter channels, or documentation.
