            Bug ID: 415530
           Summary: Plasma crashed when removing some sticky note widgets
           Product: plasmashell
           Version: 5.17.4
          Platform: unspecified
                OS: Linux
            Status: REPORTED
          Keywords: drkonqi
          Severity: crash
          Priority: NOR
         Component: general
          Assignee: k...@davidedmundson.co.uk
          Reporter: knackst...@outlook.com
                CC: plasma-b...@kde.org
  Target Milestone: 1.0

Application: plasmashell (5.17.4)

Qt Version: 5.13.2
Frameworks Version: 5.65.0
Operating System: Linux 5.0.0-37-generic x86_64
Distribution: KDE neon User Edition 5.17

-- Information about the crash:
- What I was doing when the application crashed:
I created 15-20 stick note widgets via the middle mouse click button. I then
started removing them one-by-one. After removing a number of them, plasma
crashed and immediately rebooted. I then started removing more of them, and
plasma crashed again.
- Unusual behavior I noticed:
Plasma was gitchy when removing the sticky note widget. The KWin desktop
effects seem to be working as intended. I can still use the alt-tab task
switcher, and I have the KWin performance monitor enabled.


Using KDE-Neon distro. Installed 2 days ago.

The crash can be reproduced sometimes.

-- Backtrace:
Application: Plasma (plasmashell), signal: Segmentation fault
