Does the "Properties" dialog work in Dolphin? Can you provide the stack trace? (It is usually logged by systemd-coredump and can be viewed with "journalctl -n 100".) Created attachment 175312 [details]

It seems to be deep in Qt6 base libraries. Also, I don't get why glib2 is used in between.
What is your exact Krusader version (git hash)?
What is your desktop environment? Plasma?
You are sure that your Arch packages, specially qt6-base and glib2 are up to date?
>ADDITIONAL INFORMATION
>NOTE: if Alt-Enter is used instead, the GUI seemingly disappears and then reappears, with the Properties dialog open. Any subsequent invocation of Properties, via context menu or shortcut, appears OK.
That indicates maybe a bug with signal/slot code. Also fits to the stack trace doing event processing.
I have the exact same software versions on Arch and still cannot reproduce it :/ A stack trace with debug symbols would be good.

Please advise about a way of getting the debug symbols in question. Created attachment 175379 [details]

When unchecking "Right clicking pops context menu immediately" in Settings - Panel - Selection mode, the first right-click causes the GUI to momentarily disapppear and then reappear (similarly to Alt-Enter) but there is no crash. I also noticed that in Dolphin in similar conditions (freshly invoked instance) the very first "Properties" invocation causes the GUI to momentarily disappear and reappear, both via the context menu and via Alt-Enter. So, there are actually two bugs here. Thanks for all the information!

According to https://stackoverflow.com/a/60143763/6286694 it is only active on special embedded systems (or for touch screens?). Is this the case for you? And what is the output of `pacman -Qi qt6-base`? In any case this looks like a bug in Qt itself and not in Krusader. The package is exactly as provided by Arch. There are no touch screens in my setup; the system is just a Dell laptop with an external screen connected. I didn't succeed to check if the issue is reproducible with X11 as the system is fully Wayland and X11 just doesn't start. alex@inspiron5620 ~ > pacman -Qi qt6-base 01:07 Name : qt6-base Version :
