I believe the Lucene file format changed in version 2.1, and your nightly .jar file is probably v2.1. See http://lucene.apache.org/java/docs/fileformats.html#Segments%20File.
I'm afraid I'm not an expert on the related compatibility issues. It has been my experience that pre-2.1 Lucene cannot read 2.1 indexes (error: can't find segments file). You seem to have shown the converse is also true...although I could have sworn that Lucene 2.1 slurped my pre-2.1 index without problems.
