Hi, I'm one of the Kalzium developers. The bug you reported is already reported in KDE's bugzilla, to be precise is #109035 (http://bugs.kde.org/show_bug.cgi?id=109035). I've recently committed a possible fix for the crash (read the one of comments made by me), so I suggest you taking a look at the bug a probably for KDE 3.5.2 the bug will be closed. Cheers, -- Pino Toscano
