I am attaching two stacktraces: one for when the actual crash happens, and another one for the first call of g_log() in the main process, which happens just before the crash. I could not figure out how to break on warnings in WebKitWebProcess. This looks like a regression in WebKit to me. Maybe you can report it upstream and then we disable the test on armhf as a temporary workaround? -- Dmitry Shachnev
