Bug 428459

Application: akonadi_imap_resource (5.15.1 (20.08.1))

Qt Version: 5.15.1
Frameworks Version: 5.73.0
Operating System: Linux 5.8.16-300.fc33.x86_64 x86_64
Windowing system: X11
Distribution: Fedora 33 (Thirty Three)

-- Information about the crash:
- What I was doing when the application crashed:

Whenever I restart one of my Akonadi IMAP resources (using Akonadi Console, since normally Akonadi does not even seem to start it anymore), it immediately crashes. I receive no emails via this resource in KMail.

The crash can be reproduced every time.

-- Backtrace:
Application: Mailbox.org  (akonadi_imap_resource), signal: Segmentation fault
