exceptions when using existing index with latest build

Building Solr last night from updated svn, I'm now getting the
exception below when I use any fq parameter searching a pre-existing
index.  So far, I cannot fix it by tweak config files, but I had to
delete and re-index.

I note that Solr was recently updated to the latest lucene build, so
maybe something broke in the index format?

here's the relevant part of the trace:

org.apache.lucene.index.ReadOnlySegmentReader cannot be cast to
org.apache.solr.search.SolrIndexReader

java.lang.ClassCastException:

Peter - I posted this to the solr-dev list this morning also.  The  
thread to follow is over there.
