Description Alexey Proskuryakov 2016-01-30 16:23:38 PST 
We have started seeing frequent assertion failures in InspectorTimelineAgent::didCompleteCurrentRecord a couple days ago. Not a lot of tests crash, but overall, this nearly blocks debug EWS.

E.g.:
http://webkit-test-results.webkit.org/dashboards/flakiness_dashboard.html#tests=imported%2Fblink%2Fanimations%2Fbase-render-style-body-crash.html
http://webkit-test-results.webkit.org/dashboards/flakiness_dashboard.html#showAllRuns=true&tests=imported%2Fblink%2Fcompositing%2Flayer-creation%2Fiframe-clip-removed.html

ASSERTION FAILED: entry.type == type

Let me try rolling out r195799 to let the bots check whether it's the culprit over the weekend.
