Alexey,
I think I'm seeing the same bug when I attempt to load CNN.com with NB r67838. The site is in the process of loading in the browser window and I experience a hang. Extensions are disabled and I still encountered. This doesn't happen with Safari 5.0.2 ( stock webkit ) on 10.6.4 but only happens on NB r67838..
Sample shows the following:
