[Scribus] pixelated images in pdf

[Eric P]

Hi there.

I've made 2 documents (20 pages and 8 pages) in Scribus so far.  Both 
are essentially a ton of photos with a little bit of text.  And in both 
documents I have had problem with a couple of the photos (seemingly 
random) being very pixelated in the pdf.

Example.

But when I export just the problem page to pdf, everything is fine 
(i.e., no unwarranted pixelation).

Here are my pdf settings.

All the imported images in this particular document (screen shots above) 
are jpg.  In the other they were pngs.  Same problem.

I've found this to be a problem with 1.2.1 and 1.2.2cvs.

Any ideas?

Thanks!
