Description Nathan Wolf 2013-03-21 18:17:23 UTC

Application: kontact (4.10)
KDE Platform Version: 4.10.00 "release 1"
Qt Version: 4.8.4
Operating System: Linux 3.7.10-1.1-desktop x86_64
Distribution: "openSUSE 12.3 (x86_64)"

-- Information about the crash:
The kmail module in Kontact wasn't showing all the mail resources.  I clicked on one that was a duplicate to expand that resource in the list-tree and the program crashed.
openSUSE 12.3 Linux 3.7.10-1.1-desktop, KDE 4.10.0 "release 1"

The crash can be reproduced some of the time.

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

New crash information added by DrKonqi

kontact (4.10.2) on KDE Platform 4.10.2 "release 556" using Qt 4.8.4

Typed in quick search field to filter out the desired folder.  After two letters, Kmail along with Kontact crashed.

Comment 2 Denis Kurz 2016-09-24 19:33:32 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 22:18:44 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.
