panic with firefox/gnash on recent -current

hi

I just installed graphics/gnash and tried to watch some flash things
on the web using firefox (fbsd native one)... on one (I tried 5?) flash 
it started to do heavy disk io and after several seconds it paniced...

I have no backtrace or anything but it doesnt seem to be hard to reproduce
but I dont have console so I cannot grab the backtrace so I hope someone
else will

thnx...
