Application: systemsettings5 (5.21.5)

Qt Version: 5.15.2
Frameworks Version: 5.81.0
Operating System: Linux 5.11.18-300.fc34.x86_64 x86_64

-- Information about the crash:
- I had removed a custom shortcut group
- I created a new custom shortcut (not in a group)
- I entered a comment
- I selected a shortcut (PrintScn in this case) 
- I opened the tab to add the command to call, and when I selected the browse option, the program crashed.

The crash does not seem to be reproducible.

-- Backtrace:
Application: System Settings (systemsettings5), signal: Segmentation fault

As announced in https://pointieststick.com/2023/07/26/what-we-plan-to-remove-in-plasma-6/ and https://community.kde.org/Plasma/Plasma_6#Removals, I'm afraid KHotKeys has reached end-of-life in Plasma 6. Accordingly, all bug reports and feature requests for it must be closed now.

Most of what KHotKeys could do can already be done with the newer KGlobalAccel system in Plasma 6. A few features such as mouse gestures and triggering conditions based on changes to window states are not yet implemented in the new system. These will be added in the future if and when resources materialize for them, and/or when a kind soul submits patches to implement them! :) Meanwhile, the 3rd-party "Mouse Actions" app (https://github.com/jersou/mouse-actions) may be usable for implementing your own mouse gestures again.

Thanks for your understanding, everyone.
