Bug#1012823: dolphin: kde crashes when dragging folder to places panel

[Will <wiiliamchung360@gmail.com>]

Package: dolphin
Version: 4:20.12.2-1
Severity: important

Dear Maintainer,

I'm not exactly sure which package has this issue, and where to find logs, any
help and direction would be appreciated.

Dragging and dropping a folder from the main viewport to the places side panel
causes kde force close, crash, and log the user out.

Steps to reproduce issue:

1. Turn tooltips on inside dolphin
- Settings > Configure Dolphin > General
- Behavior > Miscellaneous > Show tooltips [x]

2. Hover mouse over (any) folder until the tooltip shows up.
3. Drag folder to places panel with the tooltip open.
4. Observe system freeze, close, and log user out.
5. (optional) log into user, and run htop to see a program max out CPU to 100%
- It was initially korganizer, but I uninstalled it. Now it's kdeconnect.

Environment:
Freshly installed bullseye, without other repositories except for backports.
