Application: akonadiserver (5.5.90)

Qt Version: 5.9.1
Frameworks Version: 5.37.0
Operating System: Linux 4.10.0-27-generic x86_64
Distribution: KDE neon Developer Edition

-- Information about the crash:
After a minor upgrade of kde-neon stable, akonadiserver now crashes when accessing some folders. 

At the same time other messages in other folders would displayed as empty, but that was fixable by disabling local storage of IMAP folders, and then reenabling it after the cached messages expired.

The crash can be reproduced every time.

-- Backtrace:
Application: Akonadi Server (akonadiserver), signal: Aborted
Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".
