Created attachment 137842 [details] New crash information added by DrKonqi krunner (5.12.9) using Qt 5.9.5 - What I was doing when the application crashed: Now I did a right-click on the desktop and select "Execute command" from the context menu. -- Backtrace (Reduced): #6 __GI_raise (sig=sig@entry=6) at ../sysdeps/unix/sysv/linux/raise.c:51 #7 0x00007f56f64ac921 in __GI_abort () at abort.c:79 #8 0x00007f56f6c7cfb7 in QMessageLogger::fatal(char const*, ...) const () from /usr/lib/x86_64-linux-gnu/libQt5Core.so.5 #9 0x00007f56f9cd82a7 in QSGRenderLoop::handleContextCreationFailure(QQuickWindow*, bool) () from /usr/lib/x86_64-linux-gnu/libQt5Quick.so.5 [...] #12 0x00007f56f743e3d5 in QWindow::event(QEvent*) () from /usr/lib/x86_64-linux-gnu/libQt5Gui.so.5
> krunner (5.12.9) Looks like you're using a very old version. 5.12 is no longer supported; I would recommend upgrading to Ubuntu/Kubuntu 20.04 if you like LTS versions (which will get you Plasma 5.18) or Ubuntu/Kubuntu 21.04 (which will get you Plasma 5.21).
Dear Nate, thank you for your fast response! For everyone hitting the same bug: Disable the plugin "windowed widgets" in krunner. See: https://unix.stackexchange.com/a/211668/141641
