Sp2 move issue in two lang: sitemaps (and certain DB) are corrupted by a move of a page in multi-lang

If you move a validated page available in two lang (in my case a page with a main_content + a sub-page with a main_content - everything transalted in two lang and validated), in another section and then validate your move (you directly validate the destination point in the two lang), the pages appears at double in all the sitemaps (excepted the workflow one).
