next/previous buttons don't work if you have a mixed list of internet streams and FM radiostations:

To reproduce (make sure you have a mixed list of streams and fm stations)
1) Start MP
2) Goto MyRadio
3) Select an internet stream station WHERE the previous and/or the next station is a fm station
   => streamstation starts to play
4) press NEXT to switch to the fm stream => works (*)
5) press NEXT to switch to the next station
=> doesn't work, Radio keeps playing on the station selected in (4) but doesn't switch
=> PREV / NEXT buttons don't work anymore
Same problem with pressing PREVIOUS TWICE

(*) 4) works, but the name of the radio station is not displayed in the preview part (bottom left)
