DrKonqi: 5.27.5 [KCrashBackend]

-- Information about the crash:
Here's what I did to reproduce the crash every time without fail
1) The copy happens from a btrfs hdd to a folder in an ext4 ssd. The folder in
the ext4 ssd is automatically synced with syncthing with another device though
don't know how relevant that is
2) Ctrl+A and Ctrl+C 3000 files.
3) Ctrl+V to the other folder
4) Crash everytime

The crash can be reproduced every time.

-- Backtrace:
