+../src/TagListPage.cxx:41:12: error: converting to 'TagFilter {aka std::forward_list<std::pair<mpd_tag_type, std::__cxx11::basic_string<char> > >}' from initializer list would use explicit constructor 'std::forward_list<_Tp, _Alloc>::forward_list(const _Alloc&) [with _Tp = std::pair<mpd_tag_type, std::__cxx11::basic_string<char> >; _Alloc = std::allocator<std::pair<mpd_tag_type, std::__cxx11::basic_string<char> > >]'

+Fix this error by returning {{}} (a list with one empty element) instead
