            Bug ID: 457004
           Summary: plasma crashes when switching audio profile output
                    from win7 module mixer widget
           Product: plasmashell
           Version: 5.24.4
          Platform: Ubuntu Packages
                OS: Linux
            Status: REPORTED
          Keywords: drkonqi
          Severity: crash
          Priority: NOR
         Component: general
          Assignee: plasma-b...@kde.org
          Reporter: julioalfredomach...@gmail.com
                CC: k...@davidedmundson.co.uk
  Target Milestone: 1.0

Application: plasmashell (5.24.4)

Qt Version: 5.15.3
Frameworks Version: 5.92.0
Operating System: Linux 5.15.0-41-generic x86_64
Windowing System: X11
Distribution: Ubuntu 22.04 LTS
DrKonqi: 5.24.4 [KCrashBackend]

-- Information about the crash:
- What I was doing when the application crashed:
from the desktop panel (the system tray) I opened the widget "win7 volume
mixer" clicking the icon, then I clicked the speakers icon (in my case HDMI) to
check which audio profile is being used, if I do this again, next time it will
crash, this happens everytime

- Custom settings of the application:
no real custom settings, only worth noting is that both the default audio
volume icon/item and the win7 volume mixer are enabled at the same time (I have
both icons active in my system tray, which is how I want it) and I'm also using
version 26 (v26)

The crash can be reproduced every time.

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