Description Chris Kerr 2013-10-23 14:58:17 UTC 
Application: kontact (4.11.2)
KDE Platform Version: 4.11.2 (Compiled from sources)
Qt Version: 4.8.5
Operating System: Linux 3.11.4-gentoo x86_64
Distribution: "(none)"

-- Information about the crash:
- What I was doing when the application crashed:
I added a contact by right clicking on an address in KMail and choosing "Add Contact". Soon afterwards I clicked on the same address and chose "Edit Contact" and changed the name field to take into account the person's nickname. On clicking 'OK' to save the changes I was presented with a dialog (not sure of the exact wording) saying that someone else had edited the contact. I chose the button "take over changes" and kontact immediately crashed.

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

Comment 1 Denis Kurz 2016-09-24 20:55:58 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 kdepim (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 21:44:00 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.
