Description Dennis Schridde 2012-07-01 11:57:57 UTC

Application: kontact (4.8.4)
KDE Platform Version: 4.8.4 (4.8.4)
Qt Version: 4.8.2
Operating System: Linux 3.4.4-gentoo x86_64
Distribution: "Gentoo Base System release 2.1"

-- Information about the crash:
- What I was doing when the application crashed:
I changed the Akonadi database backend using the Akonadi KCM module (accessed via akonaditray -> Configure...). Then I started KMail to reconfigure my email identity's special folders. Changing the sent/drafts/templates folder of the first identity worked without issues. When I changed the drafts (or sent? Not 100% sure) folder of the 2nd account, however, KMail crashed.

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

Comment 1 Dennis Schridde 2012-07-01 11:59:45 UTC

P.S: I think it happened when I clicked OK after changing all folders. The new settings were also applied, saved and thus preserved through the crash.

Comment 2 Denis Kurz 2016-09-24 19:20:00 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 22:04:43 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.
