crash report

Since about 10 days, the WebKit nightlies crash on me seemingly randomly. I can't tell the exact revision at which it started (Is the revision somewhere in the crash report?)
It seems it's not connected to a specific website or user action, I was just reading on a site, without doing anything at the time of the crash. Thus I can't reproduce the crash, but it was still happening with r140374
