            Bug ID: 431412
           Summary: Dolphin always crashes on launch after showing
                    'Search' on title bar of ghost window for a moment
           Product: dolphin
           Version: 20.12.0
          Platform: Neon Packages
                OS: Linux
            Status: REPORTED
          Severity: critical
          Priority: NOR
         Component: search
          Assignee: dolphin-bugs-null at kde.org
          Reporter: bobby108 at live.co.uk
                CC: kfm-devel at kde.org
  Target Milestone: ---

SUMMARY
Every time I start Dolphin, it crashes. For a brief moment, a ghost window with
"Search - Dolphin" written across the title/window bar will appear for a moment
before disappearing. The crash is reported by system notification before the
ghost window appears.


The crash can be reproduced every time.
