To me it happened when loading java content (banking service) in Firefox. I don't know if that qualifies as the same bug, but it seems the results were pretty much the same.

Note: Upon trying to access the java content again I thought it crashed again, but after 1-2 mins the "Run java applet"-dialog opened and all was well.

I was checking my gmail in Chromium. Running the 64 bit port completely up to date.
