Firefox 28 application crash on reactOS that does not happen on WinXP

0.4.10-RC-30-g51a70dc gcc dbg lin, VBox 4.3.12, 1000MB RAM
Firefox 28 from rapps

Whenever I browse the website "www.tomshardware.de" the browser (reliably) crashes with unhandled exception before showing the webpages content. I tried it 3times, the last time I had break on first chance enabled to collect a stacklog. I hope it helps.
react.log

Directly afterwards I installed the same FF28 version in my WinXP SP3 VM and could properly browse that website.

The outcome seems to be not 100% reproducible, but I usually manage to crash the browser within 1-5mins.
