Description Christoph Thielecke 2016-02-24 16:55:30 UTC 
Application: akonadiconsole (0.99)
KDE Platform Version: 4.14.13
Qt Version: 4.8.6
Operating System: Linux 4.0.1-040001-generic x86_64
Distribution: Ubuntu 14.04.4 LTS

-- Information about the crash:
I started akonadi-console to reindex the contents of a kmail maildir. It started but when I did click or right click on a subfolder of the maildir, it crashed.

The crash can be reproduced every time.

-- Backtrace:
Application: Akonadi Console (akonadiconsole), signal: Segmentation fault
