Description Andreas Hencke 2016-01-08 20:04:36 UTC

Application: kontact (4.14.3)
KDE Platform Version: 4.14.13
Qt Version: 4.8.6
Operating System: Linux 3.19.0-43-generic x86_64
Distribution: Ubuntu 14.04.3 LTS

-- Information about the crash:
- What I was doing when the application crashed:
I closed some sub windows in akregator as kontact crashed.

Akgregator was pretty slow closing the windows

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

Comment 1 Denis Kurz 2017-06-23 20:54:08 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 09:54:15 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.
