Bug 420495

Application: akonadiserver (5.13.3 (19.12.3))

Qt Version: 5.14.1
Frameworks Version: 5.69.0
Operating System: Linux 5.6.4-1-default x86_64
Windowing system: X11
Distribution: "openSUSE Tumbleweed"

-- Information about the crash:
- What I was doing when the application crashed:
As, once again, many duplicates are showing up in some folders I wanted to use the "remove duplicates in folder" functionality. This makes akonadi crash every time.

The crash can be reproduced every time.

-- Backtrace:
Application: Akonadi Server (akonadiserver), signal: Segmentation fault
Using host libthread_db library "/lib64/libthread_db.so.1".
