            Bug ID: 432944
           Summary: Dolphin crashes when repeatedly trying to read file
                    from disk with I/O errors
           Product: dolphin
           Version: 20.12.2
          Platform: Neon Packages
                OS: Linux
            Status: REPORTED
          Keywords: drkonqi
          Severity: crash
          Priority: NOR
         Component: general
          Assignee: dolphin-bugs-null at kde.org
          Reporter: jens-bugs.kde.org at spamfreemail.de
                CC: kfm-devel at kde.org
  Target Milestone: ---

Application: dolphin (20.12.2)

Qt Version: 5.15.2
Frameworks Version: 5.78.0
Operating System: Linux 5.4.0-64-generic x86_64
Windowing system: X11
Distribution: KDE neon User Edition 5.20

-- Information about the crash:
- What I was doing when the application crashed:
- copy  files from a floppy disk which had bad sectors

- Unusual behavior I noticed:
- After 2 or 3 times clickin "Retry", Dolphin showed a "File overwrite?" dialog
for a second, where the file to be copied suddenly had 17kb (correct) instead
of 0kb (bad), then crashed. It seemed the disk could be read after a few
attempts, but this surprised Dolphin too much. :-p

The crash can be reproduced every time.

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