Application: akonadi_imap_resource (4.14)
KDE Platform Version: 4.14.2
Qt Version: 4.8.6
Operating System: Linux 3.17.1-1.g5c4d099-desktop x86_64
Distribution: "openSUSE 20141102 (Harlequin) (x86_64)"

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

On log-in or when reconnecting to the Internet,  the IMAP resource sometimes segfaults. 
This is happening on both of the computers I use KDE on.

The crash can be reproduced sometimes.

-- Backtrace:
Application: Exovenom Mail of type IMAP E-Mail Server (akonadi_imap_resource), signal: Segmentation fault
