Crash in WebKit::WebPage::didEndRequestInstallMissingMediaPlugins on vox.com

• Component: Media
• Status: RESOLVED WONTFIX

[Michael Catanzaro]

Visit http://www.vox.com/2016/4/26/11510874/oklahoma-abortion-outlaw-felony-doctors with WebKitGTK+ 2.12.2 and wait a couple seconds; it crashes 100% of the time. (You might need to uninstall extra gstreamer codecs to reproduce). It's a regression from 2.10.

I can't reproduce this bug with ToT even after removing video/mp4 and a few other mime-types from the player's mime-type set.

With my debug build I get this crash though:
