Hmm, this really looks like a Mono bug.  I don't see how this code could
fail.

Are you building from source?  If so, could you open
beagled/Lucene.Net/Index/SegmentReader.cs, and find the line:

        IMPL = System.Type.GetType(name);
        
It's really close to the end.  Before that line, add this line:

        Beagle.Util.Log.Debug ("SegmentReader class name is: {0}",
        name);
        
and after that line, add this one:

        Beagle.Util.Log.Debug ("SegmentReader class type is: {0}",
        IMPL);
        
then rebuild, rerun it, and look for the output of these two lines.

You may also want to try downgrading to Mono 1.1.13.x to see if the
problem goes away.
