Created attachment 61203 [details] log with patch and WINEDEBUG=+quartz,+gstreamer

It still crashes with your patch (tried only with builtin quartz). I attached a +quartz,+gstreamer log. (I can provide/test more stuff if needed)
So it looks like the patch helped. The crash is weird and looks like it's trying to access a DLL that was unloaded... reminds me of bug 44696.
