Plugin Croaks On <lastBuildDate> Tag

[24601]

For example, using the NYTimes feeds, it has errors like:

A plugin had an unrecoverable error. Will restart this plugin.
Plugin: <LogStash::Inputs::Rss url=>"http://www.nytimes.com/services/xml/rss/nyt/MostViewed.xml">

I am also seeing this error, looks like it could be coming from the jruby rss parser. In my case the field is 'pubDate'. Here is the output from --debug

Error: value <> of tag is not available.
Exception: RSS::NotAvailableValueError
Stack: logstash-1.5.4/vendor/jruby/lib/ruby/1.9/rss/0.9.rb:107:in `pubDate='

I am trying the plugin for the first time. I tried with logstash 1.5.5 also without sucess, the output below is from logstash 2.0.0

A plugin had an unrecoverable error. Will restart this plugin.
