            Bug ID: 400874
           Summary: Dolphin crashed on file transfer
           Product: dolphin
           Version: unspecified
          Platform: Ubuntu Packages
                OS: Linux
            Status: REPORTED
          Keywords: drkonqi
          Severity: crash
          Priority: NOR
         Component: general
          Assignee: dolphin-bugs-n...@kde.org
          Reporter: ponchorat1...@hotmail.com
                CC: elvis.angelac...@kde.org
  Target Milestone: ---

Application: dolphin (16.04.3)

Qt Version: 5.6.1
Frameworks Version: 5.36.0
Operating System: Linux 4.15.0-38-generic x86_64
Distribution: Ubuntu 16.04.5 LTS

-- Information about the crash:
- What I was doing when the application crashed:
This is a duplicate as I filed a bug report of the same crash a day or two ago,
but the crash report agent failed to find my duplicate.

What happened was I opened Dolphin and opened the location where I want the
files copied and the files from the memory card(s) to their respective save
folders, a short time elapsed and then Dolphin crashed.

The crash can be reproduced every time.

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