Thanks for this hint, Andreas; I really should have taken a look at the bug tracker the day after you filed the report. ;) After one-and-a-half thought about that issue, it is rather obvious that changing a target's location on disk after querying the location results in strange effects one way or another. So, with the improved documentation and the already obsolete LOCATION property, it's certainly alright now.
