This is a missing capability/bug in Ghostscript's PDF output device. The PDF output device does not conserve page sizes given by the input document. It always assigns the default page size or a page size given by the command line.
I have reported the problem upstream.
The CUPS task I did not remove as after the Ghostscript fix there are perhaps slight changes in the pstopdf filter needed.
