Application: akonadi_mailfilter_agent (4.14)
KDE Platform Version: 4.14.25
Qt Version: 4.8.6
Operating System: Linux 4.4.73-18.17-default x86_64
Distribution: "openSUSE Leap 42.2"

-- Information about the crash:
- What I was doing when the application crashed:

I was going through my spam box and found a few mails that shouldn't have been flagged as spam. So I created new filter rules to make sure mails from those senders would never be put in the spam box. Then I applied the filters to them using Ctrl-J.

The crash can be reproduced sometimes.

-- Backtrace:
Application: Mail Filter Agent (akonadi_mailfilter_agent), signal: Segmentation fault
Using host libthread_db library "/lib64/libthread_db.so.1".
