Bug description:
Crash on browsing watching youtube video from http://ubuntuonair.com.
Expected it to play the whole hangout video but played less than a minute.
After restarting the browser it crashed again with another random video off
youtube in less than 10 seconds. It appears to matter which video, or has
another intermittent effect.The last failing
video I've found is http://www.youtube.com/watch?v=Ir2TdfSwH8g.
Also fails on lernid, which I'm testing, and midori--both also webkit
browsers.
Running today's live i386 CD from raring. (Today == 2013-3-3).
No flash installed and therefore I assume that it is using html 5.
Running flash in lernid and midori avoids the problem as webkit seems
to use it in preference to html5--but that's just my guess.
To reproduce:
Install raring
**Don't install flash**
Install ephiphany with 'sudo apt-get install epiphany-browser'
Start epiphany from the terminal with "epiphany
"http://www.youtube.com/watch?v=Ir2TdfSwH8g
Start the video and wait for the video to stop (coincident with the halt in
the video within a minute).
