KDE 4.11.5 as well as newer KDE's show the same behavior (couldn't test Plasma 2 but I'm quite confident it applies also there).
The plasma plugins like taskbar do not respect NETWM_Type Property: The plugins properly omit windows that have NETWM::SkipTaskbar set, but as per netwm spec: http://standards.freedesktop.org/wm-spec/wm-spec-latest.html#idm140146176778320 "Applications should not set this hint if _NET_WM_WINDOW_TYPE already conveys the exact nature of the window." So applications which are of type NET::Dock or NET::Desktop should be omitted even if SkipTaskbar is not set, though they are shown in the KDE taskbar.
