[Scribus] Scribus crashing with tutorial PDF export

[Pete Phillips]

I downloaded the excellent tutorial files from
http://www.bhairon.com/gnulinux.html (fantastic work by the way).

If I load up the FYug.sla in Scribus (CVS downloaded and built today,
Sunday 16th), the document comes up OK, but if I try to export as a PDF,
I get Scribus crash message due to signal #11.

Is this a known bug, or is there anything I can do to help debug this ?
