Application that crashed: kontact
Version of the application: 4.3.5
KDE Version: 4.3.5 (KDE 4.3.5)

Operating System: Linux 2.6.31.13-desktop-1mnb x86_64

What I was doing when the application crashed:
could be a duplicate, however, this is normally a much newer KDE version... i just updated and relogged out and in.

either that, or after update there was some different config items?

I have only 2 imap accounts, it was runnig fine, and i did something else and after a little while (a few minutes) it crashed.
