Bug 456960

Application: kmail (5.20.3 (22.04.3))

Qt Version: 5.15.5
Frameworks Version: 5.96.0
Operating System: Linux 5.18.12-arch1-1 x86_64
Windowing System: Wayland
Distribution: "Arch Linux"
DrKonqi: 5.25.3 [KCrashBackend]

-- Information about the crash:
Kmail crashes every time when deleting mail and watching progress window in status bar simultaneously. After restarting Kmail, I can see that mail is always deleted. If I try to delete mail without looking in detailed progress window, it doesn't crash, but  in that case mail sometimes isn't deleted. Deletion is always successful when trash folder is changed in account settings from local folder to mail folder.

The crash can be reproduced every time.

-- Backtrace:
Application: KMail (kmail), signal: Segmentation fault
