Application: kontact (4.10.2)
KDE Platform Version: 4.10.2
Qt Version: 4.8.3
Operating System: Linux 3.5.0-27-generic x86_64
Distribution: Ubuntu 12.10

-- Information about the crash:
- What I was doing when the application crashed:
i had selected one e-mail (non-html one) and it was displayed in the bottom view. i then selected a different one (in the same folder) also text only and suddenly kmail crashed. One the selected email was quite big (5MB) and it took kmail some time to load it.
i'm using kmail for several years now and this kind of crashed never occured before. i cannot reproduce this issue, so just take a quick look and if you don't find a quick fix just close this issue as invalid.
