Created attachment 2879 proposed patch Hi, To determine if a file is supported, the plugin checks that the file returned by taglib_file_new() isn't NULL. But apparently this is not sufficient, as it would return non NULL even for weird ogg video files (because ogg is a supported filetype), and trying to display tags from them would fail, and crash thunar. The attached patch calls taglib_file_is_valid() on the obtained taglib_file, to ensure that its audio metadata are really valid, and can be displayed/queried/changed by thunar without risk.
Applied.
