[Swftools-common] segmentation faults in 0.9.0

[Digital Initiatives Studio]

Hi all,
I am currently testing the 0.9.0 version and loving it - it's fixed a 
lot of shape issues we used to get, but I have started getting a lot of 
segmentation faults. This is on a Debian 2.6.18.dfsg.1-13etch6 server, 
but I get the same on CentOS 5:
28842 Segmentation fault      pdf2swf -p 1 -s zoom=59.6 -s 
jpegquality=90 -S -z "PDFs/SA01_07.pdf" -o "hiRes/SA01_07.swf"
28844 Segmentation fault      pdf2swf -p 1 -s zoom=59.6 -s 
jpegquality=90 -S -z "PDFs/SA01_09.pdf" -o "hiRes/SA01_09.swf"
28851 Segmentation fault      pdf2swf -p 1 -s zoom=59.6 -s 
jpegquality=90 -S -z "PDFs/SA01_15.pdf" -o "hiRes/SA01_15.swf"
28891 Segmentation fault      pdf2swf -p 1 -s zoom=59.6 -s 
jpegquality=90 -S -z "PDFs/SA01_30.pdf" -o "hiRes/SA01_30.swf"
28892 Segmentation fault      pdf2swf -p 1 -s zoom=59.6 -s 
jpegquality=90 -S -z "PDFs/SA01_31.pdf" -o "hiRes/SA01_31.swf"

If you want to try and replicate the PDFs are here:

http://ps1.sk.im/7/8/78521/PDFs/SA01_31.pdf

Any help as to why they fail, and if there is a work around would be 
greatly appreciated as I can't wait to get the new version onto the 
production servers.

Cheers all,
