Stack trace doesn't make sense. Not sure how you could get from Presentation::Create to DtmfSender::RegisterObserver. Any ideas?

Status: WontFix (was: Untriaged)
ClusterFuzz testcase 6567471451734016 is flaky and no longer crashes, so closing issue.

If this is incorrect, please add ClusterFuzz-Wrong label and re-open the issue.
