            Bug ID: 502410
           Summary: Crash when dragging files over second Dolphin window
    Classification: Applications
           Product: dolphin
           Version: 23.08.5
          Platform: FreeBSD Ports
                OS: FreeBSD
            Status: REPORTED
          Keywords: drkonqi
          Severity: crash
          Priority: NOR
         Component: general

  Target Milestone: ---

Application: dolphin (23.08.5)

Qt Version: 5.15.16
Frameworks Version: 5.116.0
Operating System: FreeBSD 14.2-RELEASE amd64
Windowing System: X11
Distribution (Platform): FreeBSD Ports
DrKonqi: 5.27.11 [KCrashBackend]

-- Information about the crash:
I selected files in one Dalphin window (showing my FreeBSD partition), dragged
them over a target Dolphin window (showing my NFTF partition), and as soon as
they crossed the target windows's URL bar, the target window instantly crashed.
This hasn't happened consistently in the past but is repeatable at this exact
moment at least by restarting the target window instance and dragging from the
same source instance. It only happens when dragging over the URL bar and not
when I drag onto the window from the side instead. The file type being dragged
does not appear to matter.

The crash can be reproduced sometimes.
