Hi All, I'm a new member here and I'd like to ask about my Fedora Core's 4 Problem. I've just upgrade my fedora core 4's KDE from default to 3.5... after I upgrade I've got some crash in my KDE application like K3B. And this crash also happen when I'm shutting down my computer from KDE's session. Logs from the crash look like these : ==============================<div id="mb_0">========================================= (no debugging symbols found) Using host libthread_db library "/lib/libthread_db.so.1".
