Summary: plasmashell crashed when cancelling several FTP tasks in Notifications
Product: [Plasma] plasmashell Reporter: phd <phd>

Sentry Crash Report:

Description phd 2020-04-12 17:59:32 UTC 
Application: plasmashell (5.18.3)

Qt Version: 5.12.4
Frameworks Version: 5.67.0
Operating System: Linux 5.3.0-46-lowlatency x86_64
Windowing system: X11
Distribution: Ubuntu 19.10

-- Information about the crash:
- What I was doing when the application crashed:
I was using the Stop button in Plasma's tray Notifications widget to
stop (cancel) several active FTP commands (directories deletion).
I was clicking the Stop button of the ongoing tasks one by one.
After cancelling several of them the whole Plasma Shell froze for several seconds
(including animation for the just stopped task - slide to right screen edge)
and then Plasma Shell crashed.

- Unusual behavior I noticed:
Plasma Shell has frozen and then crashed. And it was automatically restarted.

The crash does not seem to be reproducible.

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