I have also got this bug and here it is causing system crash. This bug exists after Ubuntu 10.04, at least for me. It is reproducible by opening sites with flash content. Also for those who, this is just a logging issue, well let me say, it is not. This is real problem and it should be fixed. I am also giving my system information so that developers can fix this easily.
