Description Nick Leverton 2012-02-28 14:53:52 UTC 
Application: akonadi_imap_resource (4.7)
KDE Platform Version: 4.7.4 (4.7.4)
Qt Version: 4.7.4
Operating System: Linux 3.0.0-16-generic-pae i686
Distribution: Ubuntu 11.10

-- Information about the crash:
The IMAP connection had been interrupted by a network outage and I was getting floods of IMAP connection unavailable notifications from KDE notification manager (literally, piling up as fast as I could acknowledge them).  Closed kmail but the floods continued, even after IMAP connection was available again.  I used akonadiconsole to try to restart my IMAP agent with no change.  Then selected "Abort" for the IMAP agent and it crashed.

I've not experienced these symptoms (message floods or akonadi agent crash) before, despite the network being interrupted twice per day as I take the laptop between home and work.  What was unusual this time was that the local LAN connection remained up (as the outage was caused by IT department breaking stuff elsewhere).

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

akonadi_imap_resource (4.8) on KDE Platform 4.8.3 (4.8.3) "release 501" using Qt 4.8.1

- What I was doing when the application crashed: A network connection was restart by NetworkManager for no reason, then kmail goes to offline (grayed out) 
I've tried to restart akonadi, and everything was in state offline. Okay for me.
Then I try to reboot the workstation. and goes that crash

I also see this on a newly installed openSuSE 12.2 (rc2) with KDE 4.9 added. It does not always happen - I'll see if I can notice the pattern.
