Description Kenneth Russell 2012-06-19 16:45:56 PDT
The assertion failure below is seen in the Chromium side code while running fast/canvas/webgl/tex-image-and-sub-image-2d-with-video.html on the Webkit Mac10.5 (dbg)(1) bot. See:

http://build.chromium.org/p/chromium.webkit/builders/Webkit%20Mac10.5%20%28dbg%29%281%29/builds/8292

Flakiness dashboard:

http://test-results.appspot.com/dashboards/flakiness_dashboard.html#tests=fast%2Fcanvas%2Fwebgl%2Ftex-image-and-sub-image-2d-with-video.html

It looks like this assertion failure happens periodically and wasn't triggered by any particular change. It isn't reproducible on my 10.6 machine.
