xdg-screensaver uses the "dcop" binary from KDE3

Binary package hint: xdg-utils

Here is the problem:

$ xdg-screensaver status
/usr/bin/xdg-screensaver: line 568: dcop: command not found
ERROR: kdesktop KScreensaverIface isEnabled returned ''

The "dcop" binary still exists in Ubuntu and belongs to package kdelibs4c2a from KDE3. However I would like to run a pure KDE4 desktop therefore I purged kdelibs4c2a from my system.

There are several places where xdg-screensaver uses dcop:

$ grep -n dcop /usr/bin/xdg-screensaver
542: dcop kdesktop KScreensaverIface enable false > /dev/null
547: dcop kdesktop KScreensaverIface configure > /dev/null
552: dcop kdesktop KScreensaverIface save > /dev/null
557: dcop kdesktop KScreensaverIface lock > /dev/null
563: dcop kdesktop KScreensaverIface quit > /dev/null
568: status=`dcop kdesktop KScreensaverIface isEnabled`
