New crash information added by DrKonqi

rekonq (0.9.1) on KDE Platform 4.8.4 (4.8.4) using Qt 4.8.1

- What I was doing when the application crashed:

I was reading the news at lapresse.ca (i'm french canadian) then when i close rekong....it crash. Its not heppening frequently only when there is flash animation on the website. Is it a flash issue?
By the way i'm newbie on linux (and i'm not a programmer) so its the max i can do ;)
good luck guys
