Bug#796184: libkdecorations2-5: updating libkdecorations2-5 to 4:5.3.2-2 breaks kwin

[Bernhard Schmidt]

Control: affects 796184 + kwin-x11

I don't see the bug listed in the kwin BTS despite the affects. Possibly
because the kwin binary package doesn't exist. Marking kwin-x11 as
affected as well.
