Do you know why the package libpixman 0.30.2-2 is only available in
Trusty? (comment #35)
Is there an easy way to get that package for Saucy?
I've got that crash even if I'm updated to latest package for xorg-
server 2:1.14.5-1ubuntu2 and libpixman 0.30.2-1 (note that is -1 not

Downgraded pixman for the test (so it would actually crash)
Upgraded only xserver-common and xserver-xorg-core
It still crashes Xorg if we don't have the pixman fix..
This is trivially reproducible in a VM (I'm using vagrant/virtualbox).

- these are security patches, so you should use release-security instead of

- I'm not sure if launchpad would autoclose a bug with 'lp: #1197921' in the
