            Bug ID: 457070
           Summary: Crash when closing dolphin
           Product: dolphin
           Version: 19.12.3
          Platform: Ubuntu Packages
                OS: Linux
            Status: REPORTED
          Keywords: drkonqi
          Severity: crash
          Priority: NOR
         Component: general
          Assignee: dolphin-bugs-null at kde.org
          Reporter: pruneau at gmail.com
                CC: kfm-devel at kde.org
  Target Milestone: ---

Application: dolphin (19.12.3)

Qt Version: 5.12.8
Frameworks Version: 5.68.0
Operating System: Linux 5.14.0-1045-oem x86_64
Windowing system: X11
Distribution: Ubuntu 20.04.4 LTS

-- Information about the crash:
- What I was doing when the application crashed:
I had a few tabs open, but I cannot reproduce this consistently.
However, I was closing dolphin to work around another bug: the newly downloaded
file where not showing anymore, and restarting the app is the only way to
correct this problem.
The non-refreshing problem essentially happens when dolphin runs long enough,
it's possibly related to the crashing-when-closing (current) one.
I'll update this bug if I notice a real correlation.

The crash can be reproduced sometimes.

-- Backtrace:
Application: Dolphin (dolphin), signal: Segmentation fault
Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".
