[scribus] pdf page "leak"

[vwf]

Hello,

When I make a double sided document, and place images against the inside 
edge of a page, something interresting happens when exporting to a pdf.
When I add crop and bleed marks to the pdf export, a small strip of the 
image appears on the opposite page. Is this a bug or a feature? I would 
say it is a bug, because when making a quire(?), the image might show up
as a thin stripe.

Thank you,
Frits
