[Swftools-common] Bug report: pdf2swf segfaults

[Oskari 'Okko' Ojala]

Hello,

pdf2swf appears to segfault with some input. I have experienced this with 
a small number of some other pages too, while the majority of pages get 
converted normally.


Description of problem:
Swftools segfaults. No swf file is generated.


Steps needed to reproduce:
1. Configure, make and install swftools.
   My swftools has been configured with "--disable-lame", but I don't
   think the issue is related to that.
2. wget http://www.frantic.com/okko/swftools-bugs/segfault/1.pdf
3. pdf2swf 1.pdf --pages=1 -o 1.swf
