While fixing the problem, I realized that it was not black in Scribus
either. Sorry about that.

I looked in File -> Preferences -> Color Management. "Activate Color
Management" is not selected.

I duplicated Black, and saw that its properties were as you described.
However, the problem was fixed when I:

1) changed the colour model to RGB and set it to (0,0,0)
   The frame became black on screen in Scribus.

2) selected "Use ICC Profile" in Export to PDF -> Colors. I used the
   sRGB profile. I don't remember whether it was the default. Without
   (2), the frame was black in Scribus but not in the PDF.

I also tried exporting to PDF with scribus-ng on Kubuntu 7.04
before discovering the solution on Windows, and it seemed to work
without my having to change any default options, but I would have to
look again to make sure.

Thanks for your help.
