           Summary: Dolphin crashes when creating new folder
           Product: dolphin
           Version: 20.04.0
          Platform: openSUSE RPMs
                OS: Linux
            Status: REPORTED
          Keywords: drkonqi
          Severity: crash
          Priority: NOR
         Component: general
          Assignee: dolphin-bugs-null at kde.org

                CC: kfm-devel at kde.org
  Target Milestone: ---

Application: dolphin (20.04.0)

Qt Version: 5.14.1
Frameworks Version: 5.70.0
Operating System: Linux 5.6.12-1-default x86_64
Windowing system: X11
Distribution: "openSUSE Tumbleweed"

-- Information about the crash:
- What I was doing when the application crashed:
using context menu or F10, type a random name for the folder, dolphin crashes
when pressing ok.
stranglety dolphin does not crash if I just accept the default fodler name
("new folder") without changing it and press ok.

The crash can be reproduced every time.

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