Hi David, You made my day by fixing https://issues.apache.org/jira/browse/LUCENE-4550, THANKS!. I already applied a custom "binary patch" to my set up.
As it happens, the project I am working on is getting ready for another production release, Implementing BBoxStrategy it is not an option at this stage but I will be looking forward to upgrading to solr 4.1 in the near future.
