Package: kmail Version: 4.14.1 Debian 8.3 Searching mails is not possible. It immediately stops without any result. A solution is described here: https://groups.google.com/forum/#!topic/linux.debian.user.german/2oUv9hF3jYQ > sudo apt-get install baloo4 > akonadictl stop > akonadictl start Package 'baloo4' is missing. Stop and start is necessary as the author says. Reboot only does not help in this case. best regards, Rainer
