Hi Greg. Thanks for the tip, using "low resolution preview" the memory 
consumption was reduced from ~750MB to ~250MB on my 40 pages scribus 
doc. (Scribus 1.3.3.6)..
But... I really think that scribus needs better image handling (caching) 
so that I can see the images in its full resolution  because I need to 
do annotations about those images as an end product. Anyway 250MB for 40 
pages are a lot because the complete PDF is ~400 pages and that would 
make ~2500MB of cached low-res images; I split it in 10 pieces to make 
it workable. This sounds like a request enhancement, maybe this list is 
not for request enhancements but there it was.
Thanks.
