MOSS2007 exporting errors


I downloaded latest version of source code of MOSS2007 extractor and I found some bugs.
1) When trying to export site collection (let's say http://mossdev/) then exporter is not able to create export folder because it cannot find site name. Site name is empty string and directory creation failes.
2) When exporting only one list (I suppose this list field is there for list name) then all site tree is traversed and it seems like exporter does way more than needed. It created also folders for all other lists and subsites. I cannot understand why it is necessary to traverse whole site tree when I am importing only one list from root web.
