I think the relevant error is this one: AttributeError: 'ReleaseNotesViewerWebkit' object has no attribute '_on_navigation_policy_decision_requested' However, because you don't have all the logs attached to this report, please could you refile the bug (with the same log, but pointing out that that last line is probably the error in question)? I think that will make your report more complete.
