This update for akonadi-server fixes the following issues:

- SUSE Linux Enterprise Desktop doesn't include mysql/mariadb but SUSE Linux Enterprise Server does.
  So make mysql a Recommended (instead of Required) package when building for
  Backports and add a patch that checks in runtime if mysql is
  available before setting it as the default database and if
  it's not, use the QSQLITE3 driver (boo#1172539). Patches already
  submitted and approved by upstream.
