Bug Description

I got this crash while I was trying to watch a streaming video in Epiphany 3.18.5 from http://the-big-bang-theory-streaming.net/saison-1/episode-12/la-dualite-de-jerusalem
The video didn't play.

I think it has something to do with the flash plugin. It crashed again while I was browsing duolingo.com in Epiphany, and that website uses flash.
