Bug 287800

Application: akonadi_imap_resource (4.7)
KDE Platform Version: 4.7.2 (4.7.2)
Qt Version: 4.7.4
Operating System: Linux 3.0.0-12-generic x86_64
Distribution: Ubuntu 11.10

-- Information about the crash:
- What I was doing when the application crashed:  I put the laptop to sleep at work where I have access to my imap server.  I resumed at home where the imap server is unavailabled.  The imap handler crashed.  Instead of crashing the imap handler should fail gracefully.

The crash can be reproduced some of the time.

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