Title:
  Magick++ library broken in Ubuntu 11.10: wrong signature of
  Magick::Geometry::Geometry

Status in “imagemagick” package in Ubuntu:
  Fix Committed
Status in “imagemagick” package in Debian:
  Fix Released

Bug description:
  The signature of the Magick::Geometry's constructor has changed
  between Ubuntu 11.04 and 11.10, even though there was no change in the
  library version numbers, and no change in the upsteam code. This
  breaks any application that depends on that function.

  Upstream code, from
  https://www.imagemagick.org/subversion/ImageMagick/trunk/Magick++/lib/Magick++/Geometry.h:

      Geometry ( size_t width_,
  	       size_t height_,
  	       ::ssize_t xOff_ = 0,
  	       ::ssize_t yOff_ = 0,
  	       bool xNegative_ = false,
  	       bool yNegative_ = false );

  Ubuntu 11.04 code, in /usr/include/ImageMagick/Magick++/Geometry.h
  (equivalent to upstream):

      Geometry ( size_t width_,
  	       size_t height_,
  	       ssize_t xOff_ = 0,
  	       ssize_t yOff_ = 0,
  	       bool xNegative_ = false,
  	       bool yNegative_ = false );

  Ubuntu 11.10 code, in /usr/include/ImageMagick/Magick++/Geometry.h:

      Geometry ( unsigned int width_,
  	       unsigned int height_,
  	       unsigned int xOff_ = 0,
  	       unsigned int yOff_ = 0,
  	       bool xNegative_ = false,
  	       bool yNegative_ = false );

  Note the change from size_t to int. The header and the
  /usr/lib/libMagick++.so.3.0.0 library are both broken, though in
  different ways.

  Here's a sample program:

  #include <Magick++/Geometry.h>
  int main() {
    Magick::Geometry(0, 0);
    return 0;
  }

  It won't link on Ubuntu 11.10:

  $ g++ -I /usr/include/ImageMagick/ -lMagick++ test_magick.cc -o test_magick
  /tmp/ccghEH0m.o: In function `main':
  test_magick.cc:(.text+0x32): undefined reference to `Magick::Geometry::Geometry(unsigned int, unsigned int, unsigned int, unsigned int, bool, bool)'
  test_magick.cc:(.text+0x3e): undefined reference to `Magick::Geometry::~Geometry()'
  collect2: ld returned 1 exit status

  When compiled on Ubuntu 11.04, it will crash on Ubuntu 11.10:

  $ ~/test_magick 
  /home/dima/test_magick: symbol lookup error: /home/dima/test_magick: undefined symbol: _ZN6Magick8GeometryC1Emmllbb
