"A(nother) user recently noted on irc that progressive mode JPEG induced
huge PDFs, when not-progressive type just did fine PDFs (i'm not sure
but i seem to remember that this user said it was a new behaviour)."

This is exactly my problem. When I convert the picture and remove the
progressive mode, the resulting PDF is small.

Title:
  Automatic image compression produces huge PDF files (corverts JPG to
  bitmap)

Status in Scribus:
  Unknown
Status in scribus package in Ubuntu:
  New

Bug description:
  I am using scribus 1.4.6+dfsg-4build1 on Ubuntu 17.10 (artful). Create
  a new Scribus document and just insert one JPG compressed picture
  (Sleeping_hedgehog.jpg in my example). Then export this document as
  PDF. Use following settings in Image Compression Method:

  Compression Method: Automatic
  Compression Quality: Maximum
  Unticked Maximum Image Resolution

  The resulting PDF is multiple times bigger than the original JPG
  picture:

  $ du -sh *
  23M	Example_automatic_high.pdf
  23M	Example_automatic_maximum.pdf
  23M	Example_automatic_medium.pdf
  2,9M	Example_jpeg_maximum.pdf
  23M	Example_lossless_maximum.pdf
  12K	Example.sla
  2,2M	Sleeping hedgehog.jpg

  I expected that the resulting PDF just embeds the JPG picture without
  modifying it, but this is not the case. I don't see a way to let
  Scribus embed all JPG/PNG images unmodified in the PDF.
