Bug description:
  [ Impact ]

  Some apps (which use Cairo) crash when loadgin some svg[1] or pdf[2]
  files.

  [ Test case ]

   * Open this file with Evince: http://kernsec.org/files/LinuxSecuritySummit2012_rpm.pdf
   * Open the svg file[1] with this little program compiled with:
    $ gcc -ggdb test.c -o test `pkg-config --libs --cflags gtk+-3.0`
  Then, launch it from the same dir of the 'geany.svg' file[1]

  ===========

  #include <stdio.h>
  #include <gtk/gtk.h>

  int main (int argc, char **argv)
  {
   gtk_init (&argc, &argv);
   GdkPixbuf *pixbuf = gdk_pixbuf_new_from_file_at_size ("geany.svg", 64, 64, NULL);
   return 0;
  }

  ===========

  [ Regression Potential ]

   * The new proposed version contains a patch from Git upstream repository. It is also available in the 1.12.4 version. According to Cairo devs, it should have any regression:
    - http://cgit.freedesktop.org/cairo/commit/?id=797441093a8346003552e0cf89aef2a644ff53ab
    - https://bugs.freedesktop.org/show_bug.cgi?id=54822
    - https://bugs.freedesktop.org/show_bug.cgi?id=56698 (a duplicated bug)

  [ Other Info ]

   * This BZR branch should fix this bug: lp:~matttbe/ubuntu/quantal/cairo/lp1074667
   * You can easily test the new version by using these packages on Quantal: https://launchpad.net/~matttbe/+archive/experimental-debian-build/+sourcepub/2781148/+listing-archive-extra
   * Or on Ubuntu Raring: https://launchpad.net/~matttbe/+archive/ppa/+sourcepub/2767939/+listing-archive-extra


  [ Original bug report ]

  Hello,

  Cairo (libcairo2 1.12.2-2ubuntu1) crashes when loading some svg[1] or pdf[2] files.
  This bug has already been reported to Cairo devs:
    * https://bugs.freedesktop.org/show_bug.cgi?id=54822
    * https://bugs.freedesktop.org/show_bug.cgi?id=56698 (a duplicated bug)

  And it's already fixed in the bug-fix version 1.12.4 thanks to this commit by Chris Wilson:
    * http://cgit.freedesktop.org/cairo/commit/?id=797441093a8346003552e0cf89aef2a644ff53ab

  How to reproduce this crash:
   1] Open this file with Evince: http://kernsec.org/files/LinuxSecuritySummit2012_rpm.pdf

   2] Open the svg file[1] with this little program compiled with:
    $ gcc -ggdb test.c -o test `pkg-config --libs --cflags gtk+-3.0`
  Then, launch it from the same dir of the 'geany.svg' file[1]

  ===========

  #include <stdio.h>
  #include <gtk/gtk.h>

  int main (int argc, char **argv)
  {
   gtk_init (&argc, &argv);
   GdkPixbuf *pixbuf = gdk_pixbuf_new_from_file_at_size ("geany.svg", 64, 64, NULL);
   return 0;
  }

  ===========

  A bzr branch will be linked to this bug report: lp:~matttbe/ubuntu/raring/cairo/1074667
  This new version should fix this bug.

  How to easily test the new version:
   You can use the new version of this package available in my ppa:matttbe/ppa
   https://launchpad.net/~matttbe/+archive/ppa/+sourcepub/2767939/+listing-archive-extra

  Is it possible to upload this new package to Raring repos?
  And is it also possible to backport this change to Quantal-update repos?

  Thank you for your help! :)
