It's connected to the akonadi upgrade to akonadi 1.7.2. This bug is an on and off for years now (there is somewhere a bugreport at akonadi as well).
Most new installations will not see that, I don't know about upgrades, I ran into this bug and it was solved with a recommendation from KDE userbase: http://userbase.kde.org/Akonadi_4.4/Troubleshooting#KAddressBook_upgrade Scroll down to the chapter "To reset nepomuk and the akonadi system in KMail 2" which suggests: <pre> akonadictl stop rm -rf ~/.local/share/akonadi/db_data/* akonadictl start # we should also clean KDE temporary folders before start KMail rm -rf /var/tmp/kdecache-$USER /tmp/ksocket-$USER /tmp/kde-$USER </pre> But be aware: my addresses and distribution lists were all gone. I'm sure there is a way to get them back but I cannot be bothered at the moment to track that problem which might be connected to previous fruitless attempts to solve this bug.
