Application: kontact (4.12)
KDE Platform Version: 4.12.0
Qt Version: 4.8.4
Operating System: Linux 3.11.0-14-generic x86_64
Distribution: Ubuntu 13.10

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

I had told Kmail to autodetect the linux-btrfs mailing list information and it had seemed to be taking a while to process the folder (which has a lot of email in it), so I went away for an hour or so to do some shopping.   On my return it had crashed.

-- Backtrace:
Application: Kontact (kontact), signal: Segmentation fault
