ubuntuone music store plugin remembers and resyncs files moved out of /purchased from ubuntu one/ folder

Binary package hint: banshee-community-extensions

I've started to use the U1MS through the Banshee community extensions plugin - lovely service. However, I don't keep my music in ~/.ubuntuone/Purchased from Ubuntu One/. I keep them on my external hard drive. The files download to this directory and then I move them to my external hard drive.

The problem is that when I move them away from the folder, U1MS redownloads the files since it has a history of what I have purchased. So I end up with two local duplicates of the songs.

I'm concerned that if I do this enough times, 7digital will think that I've tried to download more than the allowed number of downloads for these songs and when I genuinely do want to recover the songs it won't allow me.

I've tried the command

 u1sdtool --list-folders
Folder list:
  id=3ef9d284-0cea-4960-8d82-cf706719eb6a subscribed=True path= ~/.ubuntuone/Purchased from Ubuntu One

u1sdtool --delete-folder=3ef9d284-0cea-4960-8d82-cf706719eb6a

But the files and folders are recreated and resync'd once more.

Lucid Lynx AMD64
banshee-community-extensions: 1.6.0-1ubuntu5
banshee: 1.7.1+git20100616.r1.ca79130-0ubuntu1+lucid
banshee-extension-ubuntuonemusicstore: 1.6.0-1ubuntu5

Steps to reproduce:
1) Purchase songs from 7digital using U1MS in Banshee
2) Move downloaded song from download folder to another folder

Expected result:
Songs are not redownloaded to the local machine

Actual result:
Songs are redownloaded to the local machine and two local duplicates now exist on hard drive
