Version: (using KDE 4.4.0) OS: Linux Installed from: openSUSE RPMs Starting with a new user akonadi creates a lot of ical resources by itself. No matter if you delete them, it will create them again and again. Also adding the same ical resource manually does not work and you cannot configure the ical resources created by akonadi.
Created attachment 40545 [details] aconadictl start output. Hope it helps.
Fixed a while ago in kdepimlibs commit a9da6ca4d9823b39a81302cb1253339a3066157f.
