Bug 476138

Application: krusader (2.8.0 "A New Day")

Qt Version: 5.15.11
Frameworks Version: 5.111.0
Operating System: Linux 6.2.0-34-generic x86_64
Windowing System: X11
Distribution: KDE neon 5.27
DrKonqi: 5.27.9 [KCrashBackend]

-- Information about the crash:
I had Krusader open and active, idle. Then I left my computer for about 20 minutes, which caused the screen to turn off (I don't have screen locking configured, only powersaving); came back to a crash. There was no queued action in Krusader. One of the panes was showing local files, the other files from a remote samba share.

The reporter is unsure if this crash is reproducible.

-- Backtrace:
Application: Krusader (krusader), signal: Segmentation fault
