My system:
Arch Linux, kernel 2.6.16, KDE 3.5.2, KMail 1.9.1

when I try to put email address in address book KMail freezing. For example:
I received eami from kde mailing list, with right button clik on kde email
address, click on Add To Address Book and KMail do nothing. I could just
closed KMail but ps -A shows that KMail running and one KMail "defunct".
