Ok, now I can reproduce the bug. I must have used combinations in my first quick check in which it didn't occur.

The problem is not the storing of the records, but the loading as it seems. When I store a record with one category applied and reopen it, a second category appears - but that second one (uid 1) is not stored in the DB-field of the record yet. By storing the record than, in some cases a third category got inserted then.

So we have to search the but inside the class "class.ux_t3lib_tcemain.php".
