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

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:

No need to mess with kde things. Your problem is crash notification, simply disable it. Right click notifications icon > Configure Event Notifications & Actions > Click Configure under Applications section > Select Plasma Workspace > Click Configure Events > In the given list, select Application Crash > Disable "Show a message in a popup" checkbox.

  • This hides the symptom of the crash, it doesn't fix the cause, kdeinit5 still crashes but it's just not shown. And when other programs crash besides kdeinit5, you'll not be notified. – Eric Sep 2 at 7:29
