SUMMARY
As in subject. Usually at evening I do update (installation after restart) next day I start my PC and login to Plasma session. After plasma finishes its start start appears pop up window next to systray calling akonadi_migration_agent, where "progress bar" moving from left to right and back. This never ending. Pressing into "Pause" button does nothing. Minimizing causes that this windows is placed in Notifications place holder and progress bar still working.

I observe this since couple months. I'm not sure what caused this.
I was installed KMail, but don't use it, because since January this year support for gmail accounts doesn't work. Only in background working some process which check emails (I have also another account added to KMail, which works)

Issue disappear when I just restart my PC.
