Bug 350559

Application: akonadi_imap_resource (4.13)
KDE Platform Version: 4.14.7 (Compiled from sources)
Qt Version: 4.8.7
Operating System: Linux 3.14.46-ck1-mainline-amdf10-rjvb x86_64
Distribution: Ubuntu 14.04.2 LTS

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

I woke the computer from sleep, unlocked the KDE wallet when requested, and then connected to the preferred WiFi hotspot (for some reason, the system connects to the weaker of my 2 WiFi networks first, half the time).

-- Backtrace:
Application: RJVB@mw of type IMAP E-Mail Server (akonadi_imap_resource), signal: Segmentation fault
Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".
