Bug 431077

Application: akonadi_maildispatcher_agent (5.15.3 (20.08.3))

Qt Version: 5.15.2
Frameworks Version: 5.75.0
Operating System: Linux 5.9.16-200.fc33.x86_64 x86_64
Windowing system: X11
Distribution: Fedora 33 (KDE Plasma)

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

Attempted to send an email from Kmail using Google SMTP. While waiting used the desktop for low-intensity tasks. Simultaneoulsy used IMAP to download new email messages.

- Custom settings of the application:

SMTP uses XOAUTH credentials over Port 587. Password used is a Google "App Password" (i.e. specific for Kmail).

The crash can be reproduced sometimes.

-- Backtrace:
Application: akonadi_maildispatcher_agent (akonadi_maildispatcher_agent), signal: Segmentation fault
