Application that crashed: kmail
Version of the application: 1.12.0
KDE Version: 4.2.98 (KDE 4.2.98 (KDE 4.3 RC3)) "release 146"
Qt Version: 4.5.2
Operating System: Linux 2.6.27.25-0.1-default x86_64
Distribution: "openSUSE 11.1 (x86_64)"

What I was doing when the application crashed:
Kmail is configured to store Passwords in KWallet.
When Kmail tries to send/receive Kwallets dialog to enter the Wallet's passpharase appears. 
If the password is entered only after some time (>5mins?) KMAIL crashes with SIGNAL 11.
