Version: (using KDE Devel) Installed from: Compiled sources I've noticed that some Gnome apps systray icons look great on KDE (e.g. liferea or acme). KMail seems not to comply with the Freedesktop System Tray Protocol Specification [http://freedesktop.org/Standards/systemtray-spec/systemtray-spec-0.1.html], so the systray icon appears as an individual window when KMail is run from a Gnome desktop.
