Application that crashed: kontact
Version of the application: 4.3.1
KDE Version: 4.3.1 (KDE 4.3.1)
Qt Version: 4.5.2
Operating System: Linux 2.6.31-server-1mnb i686
Distribution: "Mandriva Linux 2010.0"

What I was doing when the application crashed:
I let my kmail/kontact running the night, it lost the dimap connection.

Then it try to reconnect and ask if the certificate should be trusted, I answer temporary, then it reconnect.

After clicking the message box connexion was lost kmail/kontact crashed with this error.

It looks like the same problem that happen with password in kwallet late confirmation.
