Martin Gräßlin 4625d0076c [kcm-effects] Use Loader for the Video Item
Currently just opening the Desktop Effects KCM loads QtMultimedia which
in turn loads gstreamer 0.10. If one opens any other KCM in
systemsettings and changes without applying the change, the window
freezes when the warning dialog gets shown, because the warning message
pulls in Phonon with maybe the Gstreamer backend which uses
gstreamer 1.0. This is bad, bad and breaks everything.

By using a Loader the problem scope gets reduced. It still happens but
only if one actually watches a video. Only opening the KCM doesn't
trigger the problem any more.
