I tried it with same version on windows and it fails. Here is the output:

C:\projs\xml_test>xmllint --noout --version --schema 
http://www.youtube.com/xsd/metadata_0.2.xsd test.xml
xmllint: using libxml version 20623CVS2717

pattern '(.*,){2,}.*'.
test.xml:18: element keywords: Schemas validity error : Element 
'{http://search.yahoo.com/mrss}keywords': 'L,S
ci fi,Aliens' is not a valid value of the local atomic type.
test.xml fails to validate

I also validated with msxml 6 and it checks out fine so I would assume 
it is bug related to the way processing of xs:pattern element in schema.
