Bug 466503

Application: dolphin (22.12.2)

Qt Version: 5.15.8
Frameworks Version: 5.103.0
Operating System: Linux 6.1.12-1-default x86_64
Windowing System: X11
Distribution: "openSUSE Tumbleweed"
DrKonqi: 5.27.1 [KCrashBackend]

-- Information about the crash:
After disabling a 2nd monitor from the Nvidia control panel, dolphin crashes unexpectedly. Konsole is also doing this sometimes but DrKonqi fails to start. Neither Konsole nor Dolphin are not active on the 2nd monitor when it is disabled.

The reporter is unsure if this crash is reproducible.

-- Backtrace:
Application: Dolphin (dolphin), signal: Segmentation fault
