Created attachment 47465 [details] Crash log. DRT crashes dereferencing 0 pointer (see attached crash report). This happens a few times during run-webkit-test, no bad diagnostics but it makes the run longer because it waits on ReportCrash. Since Page can be created with 0 geolocationControllerClient, it seems the simple fix is to add 0 check. Patch is coming.
