The following layout test is flaky on platform GTK.
On the release build it fails sometimes. On the debug build it crashes most of the times.
When it fails, the diff is this: http://build.webkit.org/results/GTK%20Linux%2064-bit%20Release%20%28Tests%29/r170534%20%281111%29/http/tests/media/hls/video-controls-live-stream-pretty-diff.html
It's just slow here. With the default timeout value it always times out here with a release build but if I mark it slow in TestExpectations it works.
So I'm going to update the TestExpectations and close this bug for now. Feel free to reopen if the test misbehaves on the bots again.
