Description Christian Reiner 2013-07-24 10:29:51 UTC

Application: kontact (4.10.5)
KDE Platform Version: 4.10.5 "release 4"
Qt Version: 4.8.4
Operating System: Linux 3.7.10-1.16-desktop x86_64
Distribution: "openSUSE 12.3 (x86_64)"

-- Information about the crash:
- What I was doing when the application crashed:
Every time I shutdown the kontact shell I get a KCrash handler after a while (often 1-2 minutes after the shutdown). 

- Custom settings of the application:
I have the impression that this crash only happens, when knode had been enabled (used) inside that kontact session. 

This issue has been around for a few years now (if I remember correctly). Here I am referring to the dependency that knode has to be enabled to produce a crash. I failed to find prior reports for this although I remember I made one myself. Maybe they got removed because of being older?

The crash can be reproduced every time.

-- Backtrace:
Application: Kontact (kontact), signal: Segmentation fault
Using host libthread_db library "/lib64/libthread_db.so.1".

Comment 1 Denis Kurz 2016-09-24 19:19:28 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 2 Denis Kurz 2017-01-07 21:24:26 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.
