yt:display xml attribute inserted in media:credit tag causing parse failures.

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Follow the instructions on running the sample code for youtube data api 
access. gdata-samples.java-1.47.1.zip
2. The standardfeeds crashes. (Option 1)

What is the expected output? What do you see instead?
I see that the media:credit xml tags have a yt:display attribute in them. And 
this causes the parser to crash. I am not sure if this is the core problem but 
couldn't find any help on the internet.

<media:credit role='uploader' scheme='urn:youtube' yt:display='nabin 
gurung'>nabin1227</media:credit>

What version of the product are you using? On what operating system?
Latest release 1.47.1
