Version: (using KDE KDE 3.5.6) Installed from: Fedora RPMs The file dialogue in KDE has a filter. This filter requires you to type in a glob (e.g. *.png) , and press Return to activate it. Everywhere else on the desktop (e.g. dolphin, kmail), filters are instant and are partial matches. These are more user-friendly (they don't require to know globs, and they update instantly). The file dialogue should update to use this kind of filter.
Moving from "kio/kfile" component to "kfile" product, helps sorting out duplicates.
