So, I've downgraded ghostscript from 9.10 back to 9.07, renamed the
pstocanonij filter as pstocanonij-bin and wrapped it from a shell script
like this:

    #!/bin/sh
    export  LANG=C
    exec /usr/lib/cups/filter/pstocanonij-bin "$@"

And that did not make a difference. However, doing a similar thing with
the /usr/lib/cups/filter/pdftops filter (from cups-filters), did work!

I'm now reading through the code of cups and cups-filters to try to
understand why that made such a difference (and also whether there might
be a bug somewhere in CUPS), but I'd appreciate nevertheless if anyone
had any insight on this in the meanwhile.

Thanks,
Mario
