New crash information added by DrKonqi

rekonq (0.7.0) on KDE Platform 4.6.2 (4.6.2) using Qt 4.7.2

- What I was doing when the application crashed:
I'm running from a fresh install using all recent updates on a KVM guest.

Comment 2 Nuno Sucena Almeida 2011-07-07 15:13:23 UTC 
I can confirm G Narvaja report, with kde 4.6.4 on kubuntu 11.04 (64bit) and get the same backtrace , while running it within qemu-kvm 0.14.0
