Bug#989027: kate: Kate hangs (approx 30 seconds) after reassign existing keyboard shortcut.

[? <GMcPherran@Outlook.com>]

Package: kate
Version: 4:20.12.2-1
Severity: normal
X-Debbugs-Cc: GMcPherran@Outlook.com

Dear Maintainer,

1. Settings -> Configure Keyboard Shortcuts
2. Search dup
3. Assign Duplicate Selected Lines Down to Ctrl+D
4. Accept warning about replacing existing usage of Ctrl+D.

Undesired Result: Kate hangs approx 30 seconds (also may crash)

Expected result: 
Kate assigns shortcut within a second or two (or less) and returns
UI control back to the user.
