Hej Andre,

can you still reproduce it with a current version?

Ciao,
Tobias

Tested again with akonadi from trunk, Revision: 1158618
Still the same problem, according to Volker Krause this error message happens because mysql_upgrade is called every startup just in case a distribution changed the mysql Version. 

If you do not see it, do you have mysql_upgrade installed?


Output section:

SVN commit 1158741 by tokoe:

Move the mysql_upgrade call to a place where we
have made sure that mysqld is up and running and accepts
connections. This will avoid mysql_upgrade to fail with the
FATAL ERROR message.

  Do not use 'mysql_upgrade', it will call 'mysql_fix_privilege_tables'
  internally
  which prevents us from further logins. Only call 'mysqlcheck' instead,
  which
  does the checks we want to have.
