Crash

I had a crash when I tried to fetch the following URL: http://www.tatw.co.uk/podcast.xml
I also use embed.ly.

Riproduci il crash con http://www.tatw.co.uk/podcast.xml e ispeziona lib/oembed.js:115 seguendo la chiamata a DiscoveryHandler.writeTag nello stack trace. Conferma che il recupero di questo URL non causa più il crash dell’applicazione e che il comportamento di discovery di oEmbed rimane intatto.
