For users that use remote shares like NFS mounts and used amarok 2.4.0 before there is a problem when upgrading to 2.4.1: It seems that 2.4.0 had a bug that made it store remote files as local files (deviceid = -1) where the urls and the directories tables contain the full path to the files. In 2.4.1 this seems fixed: An NFS-Share will be detected correctly. This leads to the following when doing an incremental update (manually triggered in my case): All tracks from remote shares are gone and statistics are lost. What smells liek a bug is that in the urls table the rpath is set to the same value as uniqueid and the deviceid is 0 for every url.
