   Because scribus use the extension to determine the "type" of the
  file (which is, I my not so humble opinion, wrong). When it sees a
  file ending with ".ps" it calls gs to translate it to a format scribus
  likes. gs on the other hand uses the first four characters of the
  file to determine its type (independently of its name) and when
  it sees a pdf files (starting with %PDF) it interprets it as pdf,
  otherwise as postscript.
