(the KWin version is not a symptom of versionitis, but rather that we need to differentiate git master and 5.0.x packages)

Comment 1 Martin Flöser 2014-08-15 05:10:24 UTC

Please report upstream, the line in question is:
qmlRegisterType<QQuickWindow>();

[scripting] Drop qmlRegisterType for QQuickWindow

Not needed as one can just do:
import QtQuick.Window;

This fixes a build problem with Qt 5.4.
