If I type "akonadi status" in a terminal, I get QStandardPaths: wrong ownership on runtime directory /run/user/1000, 1000 instead of 0 D-Bus session bus is not available!

I am not able to restart akonadi without reboot my computer.
> QStandardPaths: wrong ownership on runtime directory /run/user/1000, 1000 instead of 0 Looks like something is modifying permissions. When this happens, check whether your user can read / write /run/user/1000. This has nothing to do with Akonadi however.
