            Bug ID: 509973
           Summary: Logout leaves stale akonadi processes on wayland
    Classification: Frameworks and Libraries
           Product: Akonadi
      Version First 6.5.0
       Reported In:
          Platform: openSUSE
                OS: Linux
            Status: REPORTED
          Severity: normal
          Priority: NOR
         Component: server
          Assignee: kdepim-bugs at kde.org

  Target Milestone: ---

SUMMARY
With a Plasma Wayland session logout leaves akonadi in a half running state and
after login PIM applications are unusable. So actually I think it is not an
akonadi problem by itself, probably more a plasma wayland issue.

STEPS TO REPRODUCE
1.  Login, make sure at least some email accounts are set up
2.  Logout
3.  Login

OBSERVED RESULT
Lots of crashes from akonadi processes, KMail/Kontact doesn't work, akonadi
cannot be restarted.

Processes still alive after logout:

ADDITIONAL INFORMATION

The state of akonadi after login:
> akonadictl stop
Akonadi is not running.
> akonadictl start
Akonadi is already running.
> akonadictl restart
Akonadi is not running.
> killall -9 akonadiserver
> akonadictl start
org.kde.pim.akonadictl: Starting Akonadi Server...
org.kde.pim.akonadicontrol: Service org.freedesktop.Akonadi.Control.lock
already registered, terminating now.
Error: akonadi_control was started but didn't register at D-Bus session bus.
Make sure your system is set up correctly!

After killing *all* akonadi processes, akonadictl start works again and the
system is usable.
