Comment 25 for bug 619003

After upgrade my 12.04, all icons and images are unrecognizable by pixbuf, all themes are affected and only see a black screen when login. I reinstall libgdk-pixbuf2.0-0 gtk2-engines-pixbuf librsvg2-2 librsvg2-common compiz metacity nvidia-304 unity ubuntu-desktop and nothing, just black screen, in the term.log see this

Processing triggers for libgdk-pixbuf2.0-0 ...
Segmentation fault (core dumped)

In the /var/log/auth.log

I try this as root

/usr/lib/i386-linux-gnu/gdk-pixbuf-2.0/gdk-pixbuf-query-loaders > /usr/lib/i386-linux-gnu/gdk-pixbuf-2.0/2.10.0/loaders.cache

But nothing, the response is

<b>Segmentation fault (core dumped)</b>

In the .xsessions.log there are several errors like this
