Rockbox

I recently encountered a quite annoying bug :
→ Go to Database, Artist, All, and play a file. Wait for all the files to be added (this is not needed though, the bug still appears if you stop the creation of the playlist)
→Now try to edit the current playing list by moving songs around.

When selecting the song, another playlist entry appears just before the actually selected one and gets moved instead of the right one. When you validate the move, it disappears and gets replaced by the track you wanted to move.
Furthermore, if you cancel by pressing ‘back’ button, the cursor jumps to the actual position of the track that had appeared. Sometimes, an empty tack is inserted, probably because the part of the playlist it comes from has not been loaded yet. Only verified on Gigabeat, not tested on other targets.
