Sentry Crash Report:

Description Tim 2021-06-01 09:59:59 UTC 
Application: kdesvn (2.1.0)

Qt Version: 5.15.2
Frameworks Version: 5.82.0
Operating System: Linux 5.4.0-73-generic x86_64
Windowing System: X11
Drkonqi Version: 5.21.5
Distribution: KDE neon User Edition 5.21

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

I just clicked the "Close" button to close the open SVN repo in "kdesvn" - everything was working alright until this point. Once I pressed the "Close" button, the "kdesvn" main window, which was showing the open SVN repository data (3 pane, one window, default layout), disappeared. I then received the notification that the application unexpectedly quit.

The reporter is unsure if this crash is reproducible.

-- Backtrace:
Application: kdesvn (kdesvn), signal: Segmentation fault
