+detection more consistent across servers.
+
+Troubleshooting
+===============
+
+In some cases this database file, 'magic', does not work with your server. You have to use the 'magic' file of your distribution, which usually comes with File 4.x on your server.
+Then in your settings.php, you add a new variable that tells Mimedetect the absolute path of the magic file to use :
+
+$conf = array(
+  'mimedetect_magic' => 'usr/share/file/magic',
+);
+
+Replace 'usr/share/file' by the magic file path if it's different on your server.
+
+Advice : first try with basic PHP, outside Drupal, if you can load the database :
+
+<?php
+$magic_file = '/usr/share/file/magic';
+$finfo = finfo_open(FILEINFO_MIME, $magic_file);
+if (!$finfo) {
+    echo "Opening fileinfo database failed";
+    exit();
+}
+?>
+
+Replace 'usr/share/file' by the magic file path if it's different on your server.
