What is the cause and how to fix this exception:
org.neo4j.graphdb.NotFoundException: More than one relationship[RTREE_CHILD, INCOMING] found for NodeImpl#105

I am using 2.0.0 and spatial jars coming from compiled github project.
The exception is thrown when I try to import Shapefile (this is code in unmanaged extension):
GraphDatabaseService spatialDb = new GraphDatabaseFactory().newEmbeddedDatabase("/home/db/data/spatial.db");
Transaction tx = spatialDb.beginTx();
try {
ShapefileImporter importer = new ShapefileImporter(spatialDb, new NullListener());
importer.importFile("/home/bla/realshp/users_location.shp", "users_location");
tx.success();
} catch (Exception e) {
e.printStackTrace();
} finally {
tx.close();
return Response.status(200).entity("Done. ").build();
}
The shape file is generated from CSV file with ogr2ogr - it seems legit and is read without exceptions. In the original file there was around 30000 points defined as follows (ogr2ogr will pull longitude and latitude):
id,longitude,latitude,gender,updated
3,-122.1171925,37.4343361,1,2013-11-20 05:03:22
304,-122.0919000,37.3094000,1,2013-11-03 00:42:01
311,-122.0919000,37.3094000,1,2013-11-03 00:42:01
How to get around it? I need to load milions of points to the db.
Side question: now I create new graph-spatial datastore - is it correct? Maybe I should load it to existing graph db?
UPDATE:
I tried to input coordinates "manually" using methods from TestSimplePointLayer. I got the same exception around 450th coordinate. Bunch of them are the same as you can see in the sample, but they are valid points. How to get around it?
