[ 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! :)
