            Bug ID: 412110
           Summary: kMail backend crashes
           Product: Akonadi
           Version: 5.12.1
          Platform: Neon Packages
                OS: Linux
            Status: REPORTED
          Keywords: drkonqi
          Severity: crash
          Priority: NOR
         Component: IMAP resource
          Assignee: kdepim-bugs at kde.org
          Reporter: merlin.chlosta+kdebugs at rub.de
  Target Milestone: ---

Application: akonadi_imap_resource (5.12.1)

Qt Version: 5.12.3
Frameworks Version: 5.62.0
Operating System: Linux 5.0.0-29-generic x86_64
Distribution: KDE neon User Edition 5.16

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

1) open the quick-start command line with Alt + Space
2) type in "mail"
- Top application entry: 'Check Mail - KMail'
- Second: 'KMail'
3) take the top entry 'Check Mail - KMail'

KMail now opens and the backend crashes, see the crash report.

As a consequence, you can't read or write mail, and have to restart the
computer if you don't know how to restart the component.

It might only appear when KMail is already open, not sure about that.

The crash can be reproduced every time.

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