            Bug ID: 453430
           Summary: Dolphin crashed after closing tab
           Product: dolphin
           Version: 22.04.0
          Platform: Neon Packages
                OS: Linux
            Status: REPORTED
          Keywords: drkonqi
          Severity: crash
          Priority: NOR
         Component: general
          Assignee: dolphin-bugs-null at kde.org
          Reporter: robert at axium.co.nz
                CC: kfm-devel at kde.org
  Target Milestone: ---

Application: dolphin (22.04.0)

Qt Version: 5.15.3
Frameworks Version: 5.93.0
Operating System: Linux 5.4.0-107-generic x86_64
Windowing System: X11
Distribution: KDE neon User - 5.24
DrKonqi: 5.24.5 [KCrashBackend]

-- Information about the crash:
- What I was doing when the application crashed:
Dolphin had 4 different tabs open and closing the fourth tab was the trigger.
Not sure what made it special, but it was largely full of executable binary
files. Closing any other tab first would allow that one to close without issue
and closing ther others seemed to work reliably. Sometimes closing the tab in
question would work without crashing, in which case opening another tab and
navigating to the folder allowed it to again be reproduced once closed.

The crash can be reproduced sometimes.

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