            Bug ID: 435427
           Summary: akonadi_imap_resource: segfault on authentication
           Product: Akonadi
           Version: unspecified
          Platform: Fedora RPMs
                OS: Linux
            Status: REPORTED
          Keywords: drkonqi
          Severity: crash
          Priority: NOR
         Component: IMAP resource
          Assignee: kdepim-bugs at kde.org
          Reporter: vmatare+kdebug at posteo.de
  Target Milestone: ---

Application: akonadi_imap_resource (5.15.3 (20.08.3))

Qt Version: 5.15.2
Frameworks Version: 5.79.0
Operating System: Linux 5.11.11-200.fc33.x86_64 x86_64
Windowing system: X11
Distribution: "Fedora release 33 (Thirty Three)"

-- Information about the crash:
The resource was working fine before and then it suddenly started crashing.
Nothing really changed except that a few new emails came in. The server is a
Microsoft 365 Exchange mailbox. I'll try to sort through the new emails, maybe
I can identify the culprit.

The crash can be reproduced every time.

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