I see occasional crash reports for kded4 (seg fault). This is a recent fresh install of F12 on new system. Seems to run OK otherwise and passes memtest86. Here is what I am running right now: $ rpm -q qt kdelibs qt-4.5.3-9.fc12.x86_64 kdelibs-4.3.4-3.fc12.x86_64 After pressing "restart app" on crash dialog: ps ax | grep kded 2800 ? S 0:00 kded4 --nocrashhandler I am also using "Fedora 12 Updates/Test Updates" and "kde-testing" repos right now. Does this sound OK? Thanks, -gene
