[YouTube-API] Error loading Video with iFrame API and Safari 5.1.2

I'm getting this error when attempting to load a video through the iFrame API on Safari 5.1.2 (OS X 10.7.2)

onPlayerStateChange[youtube:dZEF8i_embed] 1

onPlayerStateChange[youtube:dZEF8i_embed] 3

www-embed_core_module-vflv9x8EB.js:48 [  0.859s] [yt.debug] yt.tracking.VideoStatsPing: Attempted to construct a VideoStatsPing for a video that has no format or videoSize.

Any ideas?  It works fine in Safari 5.1.1, Chrome, FF

Here are the params I'm using:

 var playerVars = {"autoplay":this.autoPlay?1:0, "version":3, "autohide":this.autoHide?1:0, "showinfo":0, "modestbranding":1, "rel":0, "iv_load_policy":3, "fs":1, "wmode":"opaque", "html5":"1" }

var playerArgs = { 'videoId':this.mediaId, 'height':'100%', 'width':'100%', 'events':playerEvents, 'playerVars':playerVars }

Thanks,

Mike
