New crash information added by DrKonqi

krunner (5.25.0) using Qt 5.15.4

I updated to 5.25 and still happens. if I press alt+space nothing happens.

That is weird, could you please post your ~/.config/krunnerrc file?

Maybe running KRunner with debug output gives us a bit more context:
QT_LOGGING_RULES="kf5.krunner*=true" krunner --replace

sure:

[General]
FreeFloating=true

[PlasmaRunnerManager]
migrated=true

[Plugins]
baloosearchEnabled=true
bookmarksEnabled=false
browserhistoryEnabled=false


> QT_LOGGING_RULES="kf5.krunner*=true" krunner --replace
running that just gave:
File name empty!
No component for QUrl("")

if I press crtl+alt:
QCommandLineParser: argument list cannot be empty, it should contain at least the executable name

I see, what is your Global Theme?

> I see, what is your Global Theme?

Breeze Light.
may be relevant that the preview image doesn't show in settings.

Yes, I get the feeling that the installation is somehow incomplete. Does switching to breeze dark (if it has a preview image) make any difference?

It has the preview image but the same happens.

What does the following command give:
>find /usr/share/plasma/look-and-feel/ -name RunCommand.qml

returns the path /usr/share/plasma/look-and-feel/org.kde.breeze.desktop/contents/runcommand/RunCommand.qml

Turns out it was caused by a problem (breeze global theme missing) on my system and is resolved now :)
