This issue has been in Leopard from the beginning. There was a long discussion on MacFixit about it and people conceded that the database update was not working well, hence a slow and irrelevant permissions repair. As everybody said, you can safely ignore these. A really cheap but good upgrade of the OS, that is, Snow Leopard, took care of this problem.
