Banshee doesn't update covers on ipod

[Robin]

Following problem:

1. I import a track into Banshee.
2. The track is automatically copied to my connected iPod nano 5th generation by Banshee.
3. I change the cover of the track with Banshee
4. Banshee doesn't sync the new cover with the ipod, even if I force a sync.

Actually, I have to delete the song from the iPod, to disconnect, and then to add it again. Then the new cover is copied, too.

Instead, I want Banshee to start syncronization when a cover is changed, too.
