I agree. After I sent the previous note, I tried making a PDF from a 
file with about 80 images and Scribus crashed, I think from the memory 
issue. I'm using a machine with about 500mg RAM and 1GB of swap - 
apparently not enough. In contrast, Adobe Reader uses a whole lot less 
memory to load a file with 60 images.
