Comment 1 Nate Graham 2023-08-09 18:26:14 UTC 
Can't reproduce. Looks like it has (or had) something to do with your clipboard history. Would you be able to share it?
Comment 2 Patrick Silva 2023-08-09 19:14:12 UTC 
How can I share the whole clipboard history here?
Comment 3 Nate Graham 2023-08-09 19:38:12 UTC 
Let's see... I think it's in ~/.local/share/klipper/history2.lst.

clipboard history
Comment 5 Nate Graham 2023-08-11 16:54:36 UTC 
Thanks. However I can't reproduce the issue when I put that data into my own clipboard history.
Comment 6 Nate Graham 2024-02-05 22:15:17 UTC 
Have you been able to reproduce this with the latest Plasma 6 code?
Comment 7 Patrick Silva 2024-02-05 23:46:58 UTC 
Tested on Arch Linux running Plasma 6 RC2 and neon unstable; cannot reproduce.
