Bug 324460

Application: akonadi_imap_resource (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:

akonadi_imap_resource under KDE 4.11.0 has crashed when the PC's IP address has changed. I guess it is still the old problem that I report from time to time when there is a new KDE version and akonadi_imap_resource crashes once again on unstable network connectivity. This problem probably persists since I started to work with KDE 4 in KDE 4.3 or KDE 4.4. It really needs some debugging, since I think that probably not so few people use KDE on a laptop that changes its address from time to time when continuing to work in a different network. Then, KDE's IMAP resource gets easily out of service or even crashes. While KDE 4 itself gets better with each new version, KDE PIM and particularly its IMAP resource implementation are a steady source of frustration.
