Description totte 2014-02-19 15:09:22 UTC

Application: kontact (4.12.2)
KDE Platform Version: 4.12.2
Qt Version: 4.8.5
Operating System: Linux 3.12.6-1-CHAKRA x86_64
Distribution: "Chakra"

-- Information about the crash:
- What I was doing when the application crashed:
I received an e-mail with an invitation to a meeting (I've never seen one of those before, got to read up a bit on it) and clicked "Accept" which had the entire system slow down and especially Akonadi, KMail and Kontact - of which the latter two became more or less unresponsive.

The crash can be reproduced every time.

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

partial backtrace of kontact/korganizer related crash on exit

I observe regular crashes when exiting kontact. These happen when I have tried to accept a meeting invitation email from an exchange server. That action typically gets stuck (the 'accept' button changes its border slightly, but the reply email never gets send and no entry into  my 
calendar is made. I can keep working, but kontact crashed when I leave it. I could reproduce this behavior (three times in a row now). The observation may be related to the original bug as the crash occurs also in the messageviewer. I have posted a partial backtrace that shows that there is possibly a null pointer dereference (#19/#20).

Application: kontact (4.11.5)
KDE Platform Version: 4.11.5
Qt Version: 4.8.6
Operating System: Linux 3.13-1-amd64 x86_64
Distribution: Debian GNU/Linux testing (jessie)

Comment 2 Denis Kurz 2016-09-24 19:20:13 UTC

This bug has only been reported for versions before 4.14, which have been unsupported for at least two years now. Can anyone tell if this bug still present?

If noone confirms this bug for a Framework-based version of kontact (version 5.0 or later, as part of KDE Applications 15.08 or later), it gets closed in about three months.

Comment 3 Denis Kurz 2017-01-07 22:20:33 UTC

Just as announced in my last comment, I close this bug. If you encounter it again in a recent version (at least 5.0 aka 15.08), please open a new one unless it already exists. Thank you for all your input.
