Data::TreeDumper::Renderer::GTK makes brother objects children

[Ari Jolma <ari jolma tkk fi>]

I have an object, dumped below with Data::TreeDumper. When I put the 
same object to Data::TreeDumper::Renderer::GTK ogr_driver becomes the 
son of  ogr_datasource, ogr_layer the son of ogr_driver etc. I don't 
understand why. Otherwise the tree is ok. Anybody have any ideas?
