            Bug ID: 405990
           Summary: Akonadi Crashes on every KDE Login
           Product: kontact
           Version: unspecified
          Platform: Neon Packages
                OS: Linux
            Status: REPORTED
          Keywords: drkonqi
          Severity: crash
          Priority: NOR
         Component: general
          Assignee: kdepim-bugs at kde.org
          Reporter: linux at osit.cc
  Target Milestone: ---

Application: kontact (5.10.1)

Qt Version: 5.12.0
Frameworks Version: 5.56.0
Operating System: Linux 4.18.0-16-generic x86_64
Distribution: KDE neon User Edition 5.15

-- Information about the crash:
I've worked a long time with Kontact on KDE NEON. Since a Week Akonadi crashes
on every Userlogin to the desktop. If i restart Akonadi on cli it works again
fine for some time. After some houers on Korganizer i can't choose different
calenders. So another restart is needed. 

I've setuped 6 IMAP Mailboxes and one Nextcloudserver. 

If you need more informations pleas feel free to contact me. 
Thanks a lot :)

The crash can be reproduced every time.

-- Backtrace:
Application: Kontact (kontact), signal: Segmentation fault
