Application that crashed: kontact
Version of the application: 4.3.0 rc1
KDE Version: 4.2.95 (KDE 4.2.95 (KDE 4.3 RC1))
Qt Version: 4.5.2
Operating System: Linux 2.6.30.1-server-1mnb i686
Distribution: "Mandriva Linux 2009.1"

What I was doing when the application crashed:
Same bug still valid

It's just required to set kwallet opening to ask each time and wait before validating the kwallet opening request.

Then kontact and kmail will crash.
