Description boospy 2019-03-29 14:02:15 UTC 
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.
