I keep experiencing the same crash on my G5 with Safari very frequently. It happens on any webpage and does the same thing every time. It freezes, one CPU will go down to around 20% usage and one will ramp up to 100% and after a few seconds Safari will close. The only mod I've made to it is faking the version number to 7.1.6. Also, the crash happens more in Web Kit, although using regular Safari it does still happen. Edit: I'll just upload two text files here. Tff is crashing as well, had to boot into Tiger.
