          Platform: Kubuntu Packages
                OS: Linux
            Status: REPORTED
          Severity: normal
          Priority: NOR
         Component: view-engine: details mode

  Target Milestone: ---

Application: kdeinit5 (20.08.2)

Qt Version: 5.14.2
Frameworks Version: 5.74.0
Operating System: Linux 5.8.0-33-generic x86_64
Windowing system: X11
Distribution: Ubuntu 20.10

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

viewing directory of png images (each opened in gwenview) from a sub directory.
Each dir has about 200-300 images. Had sub dir expanded (wasn't navigating to
sub directory).
After viewing several images (and closing them in gwenview) Dolphin crashes.

The crash can be reproduced sometimes.

-- Backtrace:
Application: Dolphin (kdeinit5), signal: Segmentation fault
