I did manage to fix this. I basically replaced the function,
static SWFFONT* gfxfont_to_swffont(gfxfont_t*font, char* id)  from
swfoutput.cc with the one from the development version. I discovered
that the only six bytes that were different from the swf produced by
swftools-0.7.0 and the dev version were those corresponding to the

swffont->layout->ascent
swffont->layout->descent
swffont->layout->leading

Once these were initialized, textsnapshot works!

I have just posted a new bug #20 regarding

however, I cannot seem to upload the pdf file that is causing this, it
is around 1.5M. I'll try sending it to you as an email attachment.

Best,
