Bug 465077

Application: krusader (2.8.0 "A New Day")

Qt Version: 5.15.8
Frameworks Version: 5.102.0
Operating System: Linux 6.1.8-1-default x86_64
Windowing System: X11
Distribution: "openSUSE Tumbleweed"
DrKonqi: 5.26.90 [KCrashBackend]

-- Information about the crash:
When I connect or disconnect an external screen via a USB-C hub to my laptop put to sleep and wake it up, Krusader crashes. The crash happens in about 70-80% of connection changes. As I remember it also happened when the laptop was not sleeping.

The crash can be reproduced every time.

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