-- Information about the crash:
Program error Krusader, if you do display the contents of the window on the left of the window - right. In the left window, start unpacking archive-RAR. Archive-RAR should be password protected.

krusader (2.7.2 "Peace of Mind") using Qt 5.15.5

I think I hit the same bug today with up-to-date (as of 2022-08-19) KDE Neon.

I opened a regular ZIP archive in the right panel, the archive didn't display anything, only the "busy" mouse cursor; then I hit the key cmbo to display the archive contents in the other pane, too, and Krusader crashed.
I don't think there's anything special about the ZIP archive, it's a regular 5MiB file, no password protection.
