--- Comment #2 from O. Puetz <opuetz at web.de> ---
I can confirm this malloc crash happening in different akonadi modules at
first. Running a test system without akonadi, kded crashed with the same malloc
error after a while (run time varies).
Test system config and tested software versions:
- AMD Phenom II with 16GB RAM
- openSUSE Leap 42.1
- Qt 5.6.0 and now 5.6.1
- KDE Frameworks 5.2.1 and now 5.2.2
- Plasma 5.6.3 and now 5.6.4
- KDE:Applications 16.04.1

To me it seems this is no KDE PIM bug, it should be in some of the underlying
software layers. And may be related with specific hardware config.
Wiping /tmp seems to help at first, but it just allowed akonadi to start
successfully and after an undetermined time a malloc error appeared again (e.g.
in akonadi imap resource).

BTW, an identical setup in a VirtualBox machine runs without these malloc
crashes.

Some other users are faced with the same or similar problem, see
