Created attachment 175891 [details] Screenshot showing the discrepancy of the calendar, its config file and the config kcm SUMMARY Technically this bug is in kdepim-addons, but since I couldn't find that as a product, submitted here as this is where it is visible. Feel free to move as appropriate. I assume that due to current efforts in porting stuff around with kdepim-addons, the actual kcm shown when configuring the calendar / digital clock and enabling calendar events no longer works. It does show all available calendar sources, but their state does not reflect their actual state, as they are all unchecked. Changing the config also doesn't add/remove a calendar, as one would expect, and closing and re-opening the config puts it back into the "everything unchecked" state. STEPS TO REPRODUCE 1. Configure the digital clock 2. In calendar, enable the calendar events plugin 3. Go to the configuration of calendar events OBSERVED RESULT All unchecked, kcm neither shows the current state nor work, at all. EXPECTED RESULT kcm shows the current configuration state and allows to change it Side note: editing plasmashellrc in a text editor and adding / removing the ids extracted from akonadiconsole does work.
