Opera 12 crashes on clicking outgoing links on Facebook
===

My problem is as follows: 

Since my Update to Opera 12 (from Opera 11.6x) the browser crashes every time I click a link on Facebook that leads to another website.

As I have about 80k mails in Opera mail that I don't want to lose, a simple: delete everything, start from scratch is not good. Which files could cause the problem and how do I keep my mails save from uninstalling/reinstalling Opera?
