Where do I report this bug?
It started not logging in or out the way it's supposed to.
When I rebooted it was running numerous stop jobs for sessions that were logged out.
I went here:

and did this:
Removing Akonadi & KDE PIM suite
If you don't need the KDE PIM tools, you can uninstall the Akonadi framework.
Keep in mind to do this you cannot use neither Mageia Control Center nor urpme as that would remove your whole KDE installation due to the inter-package dependencies. The following command should be able to remove Akonadi, but keep some essential packages:
rpm -e --nodeps $(rpm -qa | grep akonadi | grep -v -e akonadi-kde4 -e akonadi-kmime4 -e akonadiprotocolinternals)
To also uninstall the KDE PIM tools themselves (for whatever reason) you could use the following:
rpm -e --nodeps $(rpm -qa | grep -e kdepim -e kpim -e pimcommon)
Things seem to be working the way they should now.
