    Description

      A dump of a table with a UNQUE KEY cannot be restored. Error: ERROR 1032 (HY000) at line xx: Can't find record in ...
      However, mysqldump with option --skip-disable-keys creates dumps, that can be restored.
      So the workaround is to create dumps with this option set instead of the default option --disable-keys
      The problem is located in the following line of the dump:
      /*!40000 ALTER TABLE `seiten` DISABLE KEYS */;

      we can reproduce the error with this dum file of a table "seiten":

      when the line

       /*!40000 ALTER TABLE `seiten` DISABLE KEYS */; 
      

      is removed the dump can be restored.
