Gtkpod fails to launch

Today I've tried to use Gtkpod but nothing happens.
If a program fails to launch , I lauch it on a terminal to know what the problem is.
The problem is a segmentation fault ; with a simple research on google (here), I have found out that the responsible of this problem is libanjuta (a dependence of gtkpod).

1) open a shell :

sudo nautilus /var/cache/pacman/pkg/

2) search libanjuta ; you should have at least two packages , an older one and a new one. Write down the name of the older package (in my case :3.8.4-1-x86_64.pkg.tar.xz)

3) open a shell again:

sudo pacman -U /var/cache/pacman/pkg/libanjuta-3.8.4-1-x86_64.pkg.tar.xz

You should be able to use gtkpod now (perphaps with some little graphic issues).
