After upgrading Kubuntu from 18.04 to 18.10 and that to Plasma 5.14.5 through the "backports" PPA I am lucky enough to face almost no bugs, except annoying notifications saying "kdeinit5 closed unexpectedly"

enter image description here

It happens when I take some normal actions in Dolphin: start a new window, new tab, split, refresh.

It seems to me that those actions are related to the Dolphin window; creating a new folder or deleting something doesn't trigger the error.

I read here that kdeinit5 is a process launcher that executes KDE programs and kdeinit loadable modules (KLMs) starting them more efficiently. Using kdeinit5 to launch KDE applications makes starting a typical KDE application a couple times faster and reduces memory consumption by a substantial amount. - But as far as I can tell only Dolphin reports a problem with that.

I have not noticed Dolphin operation or that of any part of the desktop being affected at all by this, I would just like to avoid seeing those notifications.

Of course, I would like to have a solution that would avoid the error in the first place, but - if that is not possible until a future update etc - I am mainly asking here for a way to simply make those notifications go away.


I don't know how to debug this, or if the following is useful, but running kdeinit5 dolphin the file manager starts with the usual error while in terminal I get this:
