Description Martin Steigerwald 2010-05-06 11:25:20 UTC

Version:           akonadi 1.3.1-3 debian packages (using KDE 4.4.3)
OS:                Linux
Installed from:    Debian testing/unstable Packages

Often, possibly always Akanodi complains about dbus session bus not having been shut down on first start of Kontact after starting a new KDE session:

martin@shambhala:~/.local/share/akonadi> cat akonadi_control.error.old 
D-Bus session bus went down - quitting 
martin@shambhala:~/.local/share/akonadi> cat akonadiserver.error.old 
D-Bus session bus went down - quitting 

Since these are previous error logs, could this point at a race condition when shutting down the previous KDE session? Obviously the DBUS session bus should be closed after Akonadi has been quit.

Expected results:

No error messages for regular starting of Akonadi that confuse the user.

I am using:

Bug #236535 and bug #236538 happen at the same first start of Akonadi.

This part should be fixed with akonadi from branch

Comment 5 Martin Steigerwald 2010-06-07 14:14:44 UTC

Hmmm, I think thats not an error message at all. When I quit the KDE session the dbus session related to it wents down for sure.

If its just an informational message it might better be removed, since thats an error log.

Comment 6 Volker Krause 2010-08-02 16:02:10 UTC

The D-Bus startup race has been fixed in Akonadi server >= 1.4.0 and KDE >= 4.5.0.
