Application that crashed: kontact
Version of the application: 4.3.2
KDE Version: 4.3.2 (KDE 4.3.2)
Qt Version: 4.5.3
Operating System: Linux 2.6.31.5-desktop-1mnb x86_64
Distribution: "Mandriva Linux 2010.0"

What I was doing when the application crashed:
when loggin in, kamil is always double restored (seesion management bug?)

I closed one of both kmail windows and kmail crashed.

Windows were iconified, so I right clicked the kmail<2> windows and selected close.

and boom
