Description Con Kolivas 2018-07-24 09:41:03 UTC 
Application: kmail (5.7.3)

Qt Version: 5.9.5
Frameworks Version: 5.44.0
Operating System: Linux 4.17.2-ck1+ x86_64
Distribution: Ubuntu 18.04 LTS

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

Kmail crashed when I shut it down.

More info:

Kmail was unable to move emails due to email management hanging whenever it sees a .ics file in an email in my imap inbox. This happens with 100% reproducibility. I usually close kmail and open akonadi console to clear the cache and restart akonadi server - which crashes 100% of the time when I do that too but am unable to submit a bug report since there are no debugging packages.

The crash can be reproduced every time.

-- Backtrace:
Application: KMail (kmail), signal: Segmentation fault
Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".
