Bug report for navigation issue

[JessyJP]

Generally there shouldn't be repeated entries in the service but if there are the next and previous actions (calls) from the server act very weird. Kind of like forming a loop. This has been tested with the latest master updates.
Example; ... A , B , C , D , E , B , H... starting from A the H item will not be reached simply by pressing next on the remote control, it will go in a loop.
