persistent dpkg error - libxrandr2

[richard lyons <richard@the-place.net>]

Sarge - aptitude:
For some weeks now, every time I install anything, I get
 dpkg: error processing \
  /var/cache/apt/archives/libxrandr2_4.3.0.dfsg.1-1_i386.deb \
  (--unpack):
 trying to overwrite '/usr/X11R6/lib/libxrandr.so.2.0', which \
  is also in package xlibs
 dpkg-deb: subprocess paste killed by signal (Broken pipe)

But I cannot remove libxrandr2 because icewm, kcontrol, and 
libgtk2.0-bin depend on it.  So it just stays there, partly 
installed.  Nothing is obviously broken as a result, and I assumed 
this was just a minor bug that would get mended soon.  It remains 
there week after week, and I am now wondering whether I am doing the 
wrong thing (masterly inactivity).  Is there a debian way to respond 
to issues like this that I haven't yet understood?
