I have a document in Scribus. When exporting it as a pdf and opening it in Acrobat, Acrobat crashes. It happens either when I scroll quickly in Acrobat or when I run pre-flight.
The document is 40 pages long and has approximately 20 pictures (which I scale down to 300 bpi when exporting to pdf).
To remedy the problem, I have tried the following:
* Exported other pdf:s of the same size and opened them in Acrobat: Same problem.
* Exported smaller pdf:s and opened them in Acrobat: Acrobat still scrolls slowly, but I get fewer crashes. (With small enough document, no crashes.)
* Open other large pdf:s made in InDesign and open them in Acrobat: Works perfectly.
* Open my pdf in another pdf-handeling program (PStill): It also crashes.
* Installed Acrobat on another computer and opened my pdf: Same problem. Acrobat crashes also on this computer.
* Called Adobe-help who tried for 2.5 hours and came to the conclusion that the pdf must be corrupt.
So this is also my conclusion: Scribus generates corrupt pdf:s, and the errors reveal themselves in Acrobat when the pdf:s excceed 35:ish pages.
I have spent 3-4 days on this problem now, so I would appreciate all help.
