Grégoire, I took a quick look at SearchHandler:242, but it looks like figuring out where this class cast exception came from would require debugging (which you may have to do on your end). There is no patch to apply for distributed search -- what's in the trunk already has distributed search functionality and it works (I've used it), though there are still improvements to be made (e.g. SOLR-502, etc.)
