Constant plasmashell error/warning "Unable to assign [undefined] to (...)" in Plasma 5.15


#1

Hello,
anyone has any solution to this nagging issue? Whenever an app, especially GTK one, is showing any window or user interacts with it there’s a ton of entries in logs related to 2 positions in plasmashell modules/files:

plasmashell[844]: file:///usr/share/plasma/plasmoids/org.kde.plasma.taskmanager/contents/ui/Task.qml:343: Unable to assign [undefined] to int
plasmashell[844]: file:///usr/share/plasma/plasmoids/org.kde.plasma.taskmanager/contents/ui/Task.qml:367: Unable to assign [undefined] to QString

Any one knows of a solution to this?

Whats in there?
cat /usr/share/plasma/plasmoids/org.kde.plasma.taskmanager/contents/ui/Task.qml

BTW - I’m using icon-only task manager so I dont seethe same … but I have some similars stemming from lock/clock/userdelegate from breeze theme (Ithink this has to do with me messing with lockscreen theme … will have to check further later)
And in that case … there are literally intries with ‘undefined’ in them:

            style: softwareRendering ? Text.Outline : undefined
            styleColor: softwareRendering ? ColorScope.backgroundColor : undefined

#3

AFAIK it’s some task management for the Qt framework to manage a lot of UI stuff in KDE/plasma… Though it is, it seems, quite an old piece of the KDE environment (as stated in the file):

Was that all of it? Cuz mine has dozens of lines

Of course not… I’ve quoted only the first line :wink:

Do you have those as well?
Or maybe do you know of a fix for these?


#7

Yeah … mine are the same.

The guess is of course that GTK apps arent returning identifiers as QT expects them … but honestly, I have no idea. Maybe someone knows better.


#8

Seems GTK apps tend to overgenerate these errors, but even simple going through KDE system settings or selecting items for and from the panel or the main menu does generate those entries in logs… Mayhaps someone here is apt enough with KDE/kwin/plasmashell to offer some assistance and fix this…
