Version:            (using KDE KDE 3.4.2)
Installed from:    Mandriva RPMs
OS:                Linux

It starts right after logging in into KDE session.  At first (it started happening 2 days ago) it would display signal8 message once right after logon finished and the desktop and icons were fully displayed. Today it started happening repeatedly (as soon as I close one message it displays another and so ad infinitum. If I use GNOME than it crashes once after logon and it doesn't happen again until the next logon, so I can work in GNOME session but not in a KDE.

This is the Backtrace display:
