            Bug ID: 414607
           Summary: Plasmashell crashes after hovering mouse over the
                    panel
           Product: plasmashell
           Version: 5.17.3
          Platform: Archlinux Packages
                OS: Linux
            Status: REPORTED
          Keywords: drkonqi
          Severity: crash
          Priority: NOR
         Component: general
          Assignee: k...@davidedmundson.co.uk
          Reporter: sebastiankuz...@gmail.com
                CC: plasma-b...@kde.org
  Target Milestone: 1.0

Application: plasmashell (5.17.3)

Qt Version: 5.14.0
Frameworks Version: 5.64.0
Operating System: Linux 5.3.13-1-ck-k10 x86_64
Distribution: "Arch Linux"

-- Information about the crash:
- What I was doing when the application crashed:
Playing a game. Kwin just returned from suspending effects. I hovered a mouse
over the panel to launch firefox. This crash happens randomly, however hovering
mouse over the panel seems to increase freqency of showing it.

The crash can be reproduced sometimes.

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