produces as many windows as songs in the view when the decoder is not installed
Submitted by Baptiste Mille-Mathias
I added songs in gnome-music (system installed) and when I tested gnome-music from jhbuild mp3 decoder was not installed, I launched an album and gnome-music created several messagebox stating the decoder was missing. Actually it created as many message boxes as they are songs in the album.
obviously it should only produces one messagebox or provide another way to inform the user there is a missing decoder.
