[scribus] scribus crashes when adding pages

[vwf]

Hello,

I have a serious problem. I cannot add pages to my book (92 pages right
now). If I try to add 4 pages (the last four) it chashes:
[...]

Scribus crashes due to Signal #6
Calling Emergency Save

As you can see, I run 1.3.5rc2 on Lenny/Debian. I cannot run rc3 because
of dependency problems of the rc3 packages. Can someone tell me what to do?
The book my see its first release next week.

Thank you,
Frits
