There was recent change in the line where the test is crashing (https://webkit-search.igalia.com/webkit/source/Source/WebCore/platform/graphics/gstreamer/TextSinkGStreamer.cpp#67), but I think it's unrelated since the test has been crashing sporadically before that.

The test doesn't seem to crash in Debug.
