When I moved a track in current playlist(not saved ones or dynamic) , say from second in list to first position, guayadeque added the same track once more at the bottom of the playlist. I'm using the lastest svn version.
Same behaviour here. When dragging around a track in the playlist the mouse pointer changes into a document with "+" sign. After dropping the track an additional copy of the same track is added to the end of the playlist.
I can confirm this problem as well under openSuse 12.1/Gnome 3 running gnome shell, 1798 as well, but it's been present for a while. Sorry I never got around to posting about it but I forget as I never really drag and drop.
Is there another way to re-arrange track order in the playlist? I tried using various key-combination to no avail. It looks like there is only drag and drop possible. So far this additionally requires deleting all duplicated tracks at the bottom.
