Version: (using Devel) Installed from: Compiled sources If you 1) start akonadiconsole 2) stop akonadi server 3) rm ~/.config/akonadi/* 4) start akonadi server all the deleted agents are still shown in akonadiconsole's Agents tab.
This bug has only been reported for versions older than KDEPIM 4.14 (at most akonadi-1.3). Can anyone tell if this bug still present? If noone confirms this bug for a recent version of akonadi (part of KDE Applications 15.08 or later), it gets closed in about three months.
Just as announced in my last comment, I close this bug. If you encounter it again in a recent version (at least 5.0 aka 15.08), please open a new one unless it already exists. Thank you for all your input.
