When a new search playlist is created, we are allowed to not fill any "search lines" with our criteria. This means that when a new search playlist is created/saved, it may contain search components with empty patterns. However, when loading a search playlist from disk, we signal an error if we read an empty search pattern. As a result, the playlist does not get loaded and JuK gives the impression that it does not save the search playlists. Since we are presented with two search lines when creating a new search playlist (see AdvancedSearchDialog's ctor), the above has a rather high chance of happening. So, upon loading, we should not consider the presense of empty patterns as an error. svn path=/trunk/KDE/kdemultimedia/juk/; revision=1235482
