These failures seem to be caused by the following problems (see https://chromium-swarm.appspot.com/task?id=3802a1147288d610&refresh=10&show_raw=1);

It looks like browser_tests is failing on this machine in the same way...

The vt_video_encode_accelerator_mac.cc are likely a red herring -- they just try to create a hardware decoder for sandbox warmup. The tests themselves listed above don't use hardware decoded video.

So it looks like about 50% of the Mac 10.9 bots fail running the same set of tests;
