In comment 1, same STR as in comment 0, but with hamachi instead of unagi, and trying to load: https://www.youtube.com/watch?v=V1IBH1bz5-c Build: - gecko: b2g18:b87559cef261 - gaia: 7d0ca6a07fc3d4817f80f4ebc24314b6cbcf049a

milan, can someone on your team take a look at this? The assertion happens when B2G_DEBUG=1 on b2g18 builds; not sure if it still happens on m-c.

Peter or ChiaJung, any chance one of you can take a look?

I tried to reproduce this problem on my Unagi(2013/06/03) codebase but failed. I met another assetion fail at http://mxr.mozilla.org/mozilla-b2g18/source/dom/ipc/TabChild.cpp#507 After mark out this line, I can playback the video without problem.

I could only reproduce this issue once. Did it still happen?

I saw this today with latest m-c + patch for bug 903434. Happened after I loaded slashdot.org and changed the screen orientation a couple of times. Can't reproduce it reliably, though.
