Application: akonadiserver (5.4.3)

Qt Version: 5.8.0
Frameworks Version: 5.32.0
Operating System: Linux 4.10.5-1-ck-ivybridge x86_64
Distribution (Platform): Archlinux Packages

-- Information about the crash:
(I'm on Arch Linux running the 4.10.5-linux-ck-ivybridge kernel from the repo-ck user repo)

What has to be done to recreate the behavior:
Using any akonadi-related application after KDE startup (preferably KMail), then stopping akonadi via "akonadictl stop" or shutting down the system. It happens ONLY when booting with linux-ck kernel with the MuQQS-Scheduler enabled.

Corresponding forum thread: https://bbs.archlinux.org/viewtopic.php?id=224465

The crash can be reproduced every time.

-- Backtrace:
Application: Akonadi Server (akonadiserver), signal: Segmentation fault
Using host libthread_db library "/usr/lib/libthread_db.so.1".
