... but it was, when I remembered to use a icc-profile at least. So problem 
solved, just remember:
By 5: Use icc-profiles for all kinds of images (the Scribus standard worked 
just fine for me).
The pdf was preprinted today, and looked as it should :-D
It was then sent for final printing :-D 
(And will be delivered within a week or so :-)

... but luckily it worked anyway :-)

As said above, the pdf made with the use of the icc-profile printed just 
fine :-D
With my workaround of saving as png etc (se above) I managed to workaround the 
transparency problem. 
The printer told me transparencys are best avoided anyway, and it seems 
Scribus has serious problems with it too, so this is probably the right thing 
to do, at least for now.

Many thanks for all suggestions and help!
