I can reproduce this by loading

Adding the Mac specific signature.

Android crashes as well.  I can crash on the site as well by going to the URL and then clicking on the unsupported site link.
Same crash signature as on Mac : [@ WrapPreserve3DListInternal ]

Remove invalid assertion and add NULL check

This assertion was invalid, and we need to null check that the item has a frame.
Comment 5 Matt Woodrow (:mattwoodrow) 2011-10-03 15:29:05 PDT
Not that this patch still doesn't make the site look completely correct.

The site is using -moz-perspective:1000; (no px) which we parse as invalid, as per the spec. Webkit accepts persective numbers and treats them as pixels.

Verified fixed using Mozilla/5.0 (Windows NT 6.1; Win64; x64; rv:10.0a1) Gecko/20111018 Firefox/10.0a1. I checked the latest Mac nightly as well and no crash there.
