I have a similar issue that I haven't had a chance to track down.  I
enabled debug logging and got this:
https://gist.github.com/bdimcheff/aecc0bf49d74955b87d6#file-gistfile1-txt-L142-L143

I don't know if "Cannot process "<STDIN>": Unknown filetype." is the
cause of the problem, or if it's just what happens when the filter
fails.  In my case, it's pdf2ps that seems to be failing, but it since
ours are both filter failures, maybe they have the same cause.

You might try "cupsctl --debug-logging" to enable debug logs and see
what you get.
