Layout test http/tests/misc/cached-scripts.html sometimes crashes on the GTK EWS, but never on the release bot. The difference is that the secret service is not running on the EWS: STDERR: ** Message: Remote error from secret service: org.freedesktop.DBus.Error.ServiceUnknown: The name org.freedesktop.secrets was not provided by any .service files Although the EWS should be fixed, we also need to fix WebKit to not crash in this case.

BTW, it is a flaky crash, not something that always happens. Would be nice to have a better trace from a debug build.
