Comment 4 Liz Young 2003-12-15 19:10:22 UTC 
KDE Version (KDE 3.1.94 (3.2 Beta 2), compiled sources)
Application Integrated PIM solution
Operating System Linux (i686) release 2.4.23 (Slackware 9.1)
Compiler gcc version 3.2.3

Confirming this crash occurs here, too.  Happens when switching from mail to calendar.
