### Description

Quickshell crashed with a segmentation fault while scrolling through the application menu.

### Expected Behavior

_No response_

### Steps to Reproduce

The problem might be caused by my software shortcut, specifically the .desktop file, but I don't know which one, so I can't reproduce the issue on your devices.

### Error Messages/Logs

[report.txt](https://github.com/user-attachments/files/27052533/report.txt)

### Screenshots/Recordings

_No response_

Start by examining the attached log.qslog.log and report.txt, then inspect the reported .desktop files and reproduce the crash by scrolling the application menu. Done means the responsible application entry or menu path is identified and scrolling no longer causes Quickshell to segfault.
