Bug 358145

For an unknown reason KMail-15.12.1 refuses to work for me right from the start printing the message in console: "Failed to request resource "" : "Cannot connect to the Akonadi service. (Unable to obtain agent type ''.)"" and similar critical error box, and after I click OK it goes to segfault.

I had older versions of KDE 4.13.0 of KDE PIM and Akonadi 1.2 which I completely uninstalled according to their install_manifest.txt's, I also tried my best to clean up persistent data and configurations:
1. Removed ~/.local/share/local-mail.
2. Removed ~/.config/akonadi*
3. Removed ~/.config/kmail*
4. Removed ~/.local/share/akonadi*
5. Removed ~/.local/share/kmail
6. Removed ~/.kde/share/config/{akonadi*,kmail*}
7. Removed ~/.kde/share/apps/{akonadi*,kmail*}
8. Removed ~/.config/specialmailcollectionsrc

But it still seems to find my older version's configurations and tries to import it. Could you please reference me, what should I clean up to make it work as a with completely fresh configuration? I don't really need any migration as it seems to be broken, I just would like to set everything up once again and use it.

Reproducible: Always
