            Bug ID: 428252
           Summary: Dolphin crashes after trying to open any folder
           Product: dolphin
           Version: unspecified
          Platform: openSUSE RPMs
                OS: Linux
            Status: REPORTED
          Keywords: drkonqi
          Severity: crash
          Priority: NOR
         Component: general
          Assignee: dolphin-bugs-null at kde.org
          Reporter: ryu.ketsueki at outlook.com
                CC: kfm-devel at kde.org
  Target Milestone: ---

Application: dolphin (20.11.70)

Qt Version: 5.15.1
Frameworks Version: 5.76.0
Operating System: Linux 5.8.15-1-default x86_64
Windowing system: X11
Distribution: "openSUSE Tumbleweed"

-- Information about the crash:
- What I was doing when the application crashed:

First I was trying to open the root of the system (/). Dolphin immediately
crashed afterwards. Then I tried to open any other folder, like Pictures
(~/Pictures) and it also crashed. It's unusable.

I am using KDE Unstable repositories but Dolphin never crashed like this
before.

The crash can be reproduced every time.

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