Bug 324513

Application: kontact (4.11)
KDE Platform Version: 4.11.00
Qt Version: 4.8.4
Operating System: Linux 3.8.0-29-generic x86_64
Distribution: Ubuntu 13.04

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

Kontact 4.11.0 as crashed on user log-out. The log-out had been necessary since Kontact messed up -- again -- with the IMAP resources and changed IP addresses. "akonadictl restart" did not help.

-- Backtrace:
Application: Kontact (kontact), signal: Segmentation fault
Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".
