Overview:
I have installed gtk3 2.91.7 using http://aur.archlinux.org/packages/gtk3/gtk3/PKGBUILD and upon loading up gtk3-demo (or any program linked with gtk3) for test, it crashes with SIGSEGV.

Steps to Reproduce:

1) Try to run gtk3-demo (or any program linked with gtk3),

Actual Results:

Gtk-Message: Failed to load module "canberra-gtk-module": libcanberra-gtk-module.so: cannot open shared object file: No such file or directory
Segmentation fault

Note: I do not have libcanberra installed because of pulse compatibility (I don't have the time to mess with it right now) gtk3 worked before the upgrade to xorg 1.9 without libcanberra.

Expected Results:

A demo of gtk3.

Build Date & Platform:

Linux helium 2.6.36-ARCH #1 SMP PREEMPT Fri Dec 10 20:32:37 CET 2010 x86_64 Intel(R) Core(TM) i5 CPU M 520 @ 2.40GHz GenuineIntel GNU/Linux (Arch Linux)

Additional Builds and Platforms:

The problem does not occur with gtk2 2.22.1 on the same system.

Additional Information:
