Sentry Crash Report:

Description noucamp13 2016-04-17 18:27:01 UTC 
Application: kontact (4.14.2)
KDE Platform Version: 4.14.2 (Compiled from sources)
Qt Version: 4.8.6
Operating System: Linux 3.19.0-32-generic x86_64
Distribution: Linux Mint 17.3 Rosa

-- Information about the crash:
- What I was doing when the application crashed:
I had just restarted the computer, opened Kmail and was looking for an email when the viewing pane got hung on loading, followed by the crash.

- Unusual behavior I noticed:
On the previous session I noticed an email had disappeared from one of my inboxes, and another inbox was not loading new mails. I restarted the computer, and started again as noted above.

The crash can be reproduced sometimes.

-- Backtrace:
Application: Kontact (kontact), signal: Segmentation fault

Comment 1 Denis Kurz 2017-06-23 22:10:01 UTC 
This bug has never been confirmed for a KDE PIM version that is based on KDE Frameworks, except possibly a Technology Preview version 5.0.x. Those Framework-based versions differ significantly from the old 4.x series. Therefore, I plan to close it in around two or three months. In the meantime, it is set to WAITINGFORINFO to give reporters the opportunity to check if it is still valid. As soon as someone confirms it for a recent version (at least 5.1, ideally even more recent), I'll gladly reopen it.

Please understand that we lack the manpower to triage bugs reported for versions almost two years beyond their end of life.
Comment 2 Denis Kurz 2018-02-01 09:46:41 UTC 
Just as announced in my last comment, I close this bug. If you encounter it again in a recent version (at least 5.1 aka 15.12; preferably much more recent), please open a new one unless it already exists. Thank you for all your input.
