Application: dolphin (22.12.0)

Qt Version: 5.15.8
Frameworks Version: 5.102.0
Operating System: Linux 5.15.0-58-generic x86_64
Windowing System: X11
Distribution: KDE neon 5.26
DrKonqi: 5.26.5 [KCrashBackend]

-- Information about the crash:
KDE was running for at least more than an hour with several Vivaldi browser windows open, some of which had several tabs open. Upon closing one of the open Vivaldi browswer windows, the plasma panel task bar disappeared, and came back after about 3 seconds. A couple of other programs closed and did not automatically reopen. A couple of programs either stayed open or closed and rapidly reopened, e.g., Dolphin. There was an error message that Dolphin closed, however, I didn't actually notice because it reopened so fast.  The problem happens sometimes when closing Vivaldi browser windows, but not all the time.

The crash can be reproduced sometimes.

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