Hi,
I'm sorry but I can't say exactly "when" because it's totally random... I really don't know but this happen quite often during surfing. 
In example, when I load a webpage all seems to be ok but when I click on another tabs I get a reload for all the other tabs/windows open! After this, every time I watch the Console and WebProcess is crashed!
