--- Comment #1 from Torgny Nyblom <kde nyblom org>  2010-01-24 10:37:50 ---
Seems to deadlock due to a KJob for akonadi inside a KJob for akonadi. (#8 and
#29)
-----
FancyHeaderStyle::format()
  Akonadi::ContactSearchJob *job = new Akonadi::ContactSearchJob();
  job->setQuery( Akonadi::ContactSearchJob::Email,
KPIMUtils::firstEmailAddress( message->from()->asUnicodeString() ) );
->  if ( !job->exec() )
    return QString();

  const KABC::Addressee::List addresses = job->contacts();
-----
