@Andrex Yeah, it's well documented that it is because of the
performance_schema table.. I however disagree that it is a bug in
mysqldump; it is trying to dump that table as requested, and getting
denied (someone may very well want to dump the current stats out of that
table, and if they want to, they can do it with --skip-lock-tables)..
for the case of automysqlbackup, I'm still of the opinion that the
correct solution is to simply exclude the performance_schema table
(alongside information_schema).

Title:
  mysqldump: Got error: 1142: SELECT,LOCK TABL command denied to user
  'debian-sys-maint'@'localhost' for table 'cond_instances' when using
  LOCK TABLES

Status in “automysqlbackup” package in Ubuntu:
  Confirmed

Bug description:
  Release:	12.04
  automysqlbackup:
    Installed: 2.6+debian-2
    Candidate: 2.6+debian-2
    Version table:
   *** 2.6+debian-2 0
          500 http://us.archive.ubuntu.com/ubuntu/ precise/universe amd64 Packages
          100 /var/lib/dpkg/status


  
  After a remove --purge, reinstall of automysqlbackup, and configure in /etc/defaults/automysqlbackup, I am emailed the following error when cron runs /usr/sbin/automysqlbackup:

  mysqldump: Got error: 1142: SELECT,LOCK TABL command denied to user
  'debian-sys-maint'@'localhost' for table 'cond_instances' when using
  LOCK TABLES

  it seems that the default on ubuntu is to use the user debian-sys-
  maint to run this backup, however debian-sys-maint doesn't have full
  permissions.  Some say that these tables are not necessary to backup
  and recommend the flag " --skip-add-locks" OR "--skip-lock-tables":

  http://serverfault.com/questions/268566/cant-backup-the-mysql-table-
  with-mysqldump-select-lock-tabl-command-denied-for

  I managed to get the error to go away by adding "--skip-lock-tables"
  to /usr/sbin/automysqlbackup:


          if [ -z "${USERNAME}" -o -z "${PASSWORD}" ] ; then
                  mysqldump --defaults-file=/etc/mysql/debian.cnf $NEWOP\
  T --skip-lock-tables $1 > $2
          else
                  mysqldump --user=$USERNAME --password=$PASSWORD --host\
  =$DBHOST --skip-lock-tables $NEWOPT $1 > $2
          fi
          return 0
