Description Ivan Kalas 2013-07-27 12:48:03 UTC 
Application: akonadi_mixedmaildir_resource (4.10)
KDE Platform Version: 4.10.5
Qt Version: 4.8.4
Operating System: Linux 3.10.3-300.fc19.x86_64 x86_64
Distribution (Platform): Fedora RPMs

-- Information about the crash:
- What I was doing when the application crashed:

Kmail crashes when attempting to read certain emails. There does not seem to be any pattern. It starts with "KMail resource is broken ..." and progresses to a crash. Restarting Akonadi allows me to read 5-10 messages before KMail becomes broken again.

Here a mysql error log:

I have deleted all files in ~/.local/share/akonadi and had akonadi rebuild its database, but the problem persists.

This problem has been around since kmail2, but it became severe since I intalled Fedora 19.

The crash can be reproduced every time.

Comment 1 Denis Kurz 2016-09-24 20:32:50 UTC 
This bug has only been reported for versions older than KDEPIM 4.14 (at most akonadi-1.3). Can anyone tell if this bug still present?

If noone confirms this bug for a recent version of akonadi (part of KDE Applications 15.08 or later), it gets closed in about three months.
Comment 2 Denis Kurz 2017-01-07 22:25:22 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.
