Bug 442157

Application: akonadi_imap_resource (5.18.0 (21.08.0))
 (Compiled from sources)
Qt Version: 5.15.2
Frameworks Version: 5.85.0
Operating System: Linux 5.9.12 x86_64
Windowing System: X11
Drkonqi Version: 5.22.4
Distribution: "Gentoo GNU/Linux"

-- Information about the crash:
Sometimes, one of my imap resources "freezes" (shows no status in KMail accounts dialog), and when I pressing "restart" button, it crashes as follows.
Also it sometimes crashes on (manual) akonadiserver restarts.

Deleting the resource and recreation it from scratch helps for some time, but after som period, it gets that behaviour back...


The crash can be reproduced sometimes.

-- Backtrace:
Application: PDD (akonadi_imap_resource), signal: Segmentation fault
