Version:           1.5 (using KDE KDE 3.4.92)
Installed from:    Fedora RPMs
OS:                Linux

I start up KDE, and kdesktop crashes with pretty much the same crash as konqueror, when konqueror is pointed at a URL that has folders and icons. I'm using kdelibs-3.5.0-1.1.fc4.kde, and arts-1.5.0-0.2.fc4.kde. kdelibs was just updated via yum today through the kde-redhat-testing repository for yum. Everything was working fine prior to this (using kdelibs-3.5.0-0.2.fc4.kde).
