Comment 6 for bug 1197261

Seems that this is the problem in kde-window-manager package:
$ aptitude show kde-window-manager
Breaks: kde-style-bespin (< 0.r1552-1+), kde-style-bespin (< 0.r1552-1+), kde-style-skulpture, kde-style-skulpture, kde-window-manager-common (< 4:4.8.2a-0ubuntu2~), kde-window-manager-common (< 4:4.8.2a-0ubuntu2~), kde-window-manager-gles,
        kde-window-manager-gles, kde-workspace-data (< 4:4.8.4-0r5), kde-workspace-data (< 4:4.8.4-0r5), kdeartwork-theme-window (< 4:4.9.5), kdeartwork-theme-window (< 4:4.9.5), kdebase-workspace-bin (< 4:4.5.80), kdebase-workspace-bin (<
        4:4.5.80), kdebase-workspace-data (< 4:4.7.2), kdebase-workspace-data (< 4:4.7.2), kwin-style-crystal (< 2.2.1), kwin-style-crystal (< 2.2.1), kwin-style-dekorator, kwin-style-dekorator, kwin-style-qtcurve (< 1.8.14-2+),
        kwin-style-qtcurve (< 1.8.14-2+)

So it must be fixed in kde-window-manager package, move this issue to kde-window-manager
