Oh.. I was getting those errors too :)  I found it was because my sitemap used
'map:pipelines' inside map:components, and the syntax recently changed to

  <map:pipes default="caching">
     <map:pipe name="caching" src="org.apache.cocoon.components.pipeline.impl.CachingProcessingPipeline"/>
     <map:pipe name="noncaching" src="org.apache.cocoon.components.pipeline.impl.NonCachingProcessingPipeline"/>

Erm.  Shouldn't the sitemap version be incremented for large
backwards-incompatible changes like this?  Users are NOT going to be amused
when all their sitemaps break with such an unhelpful message..
