Bug 446692

Application: konqueror (21.08.3)

Qt Version: 5.15.3
Frameworks Version: 5.88.0
Operating System: Linux 5.11.0-41-generic x86_64
Windowing System: X11
Distribution: KDE neon User - Plasma 25th Anniversary Edition
DrKonqi: 5.23.4 [KCrashBackend]

-- Information about the crash:
-What I was doing when the application crashed:  Konqueror was open using Dolphin within Konqueror. I was moving files from one location to different location using a usb drive to transfer my files to.




- Unusual behavior I noticed: Konqueror crashed, then Dolphin gave me this message : The file or folder /home/kdeneon/Downloads does not exist. This message was with every directory within Dolphin, not just one location. My directories and folders disappeared. I can not access any of my directories, folders, or files. All is empty. no new programs added except normal daily software updates.

The reporter is unsure if this crash is reproducible.

-- Backtrace:
Application: Konqueror (konqueror), signal: Segmentation fault
