Uninstalling wine application

I installed some programs with wine. Then I uninstalled them all following the commands given in Wine Wiki. I don’t see them in the uninstallation GUI but ı couldn’t remove one thing:
When I right click on an mp3 file and choose “open file with”, winamp is still there. How can I remove it from the list?

That is in file associations. I can tell you for KDE but for gnome it is probably different.

In KDE menu Personal Settings-Advanced (tab)-File Associations.

type mp3 or mpeg. add or remove the programs associated with this extension.

Thanks a lot
