Bug 473813

Application: kmail (5.24.0 (23.08.0))
 (Compiled from sources)
Qt Version: 5.15.10
Frameworks Version: 5.109.0
Operating System: Linux 6.1.45-gentoo x86_64
Windowing System: Wayland
Distribution: "Gentoo Linux"
DrKonqi: 5.27.7 [KCrashBackend]

-- Information about the crash:
This happened while KMail was busy marking many, many thousands of messages as read for a whole (gmail) IMAP label, which had been causing 100% load for dozens of minutes, which would seem to be a bug in itself. But after kwallet popup came up before fetch for new mail, it ultimately crashed.

The crash can be reproduced sometimes.

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