HTML5 video crashes the browser

[David Barth]

In image #96 the browser can now play HTML5 video, but only once.

webbrowser-app --inspector --desktop_file_hint=/usr/share/applications/webbrowser-app.desktop http://www.w3schools.com/html/tryhtml5_video_all.htm

I am able to play the video once, but after reloading the page, the browser page gets stuck, and the console indicates:

WARNING: The web process experienced a crash on 'http://www.w3schools.com/html/tryhtml5_video_all.htm'.

The crash happens in the web process (/usr/lib/arm-linux-gnueabihf/qt5/libexec/QtWebProcess). I’m attaching a complete stack trace, manually retraced (missing the QtWebKit debugging symbols, as both the device and my laptop run out of memory when retracing with them).

I’m suspecting a gstreamer issue (maybe in gstreamer-hybris?), attached is a slightly more interesting stacktrace, see threads 2 and 23.

Here is a sample video content page to reproduce the issue: http://people.canonical.com/~davidbarth/html5video.html

The video should play (relatively) fine the first time. Then reload the page and it crashes.

I also made this click package to simplify the reproduction of this issue on a real web service: http://people.canonical.com/~davidbarth/click/com.ubuntu.developer.webapps.webapp-dailymotion_1.0.0_all.click
