Maybe it's not related... but I prefer to register here. I use Trusty for some months (3,4...) and the last one or two dist- upgrades just got me out of my Unity Desktop. GUI login did not complete (always back to login), default wallpaper not shown, topbar not shown (icons, etc). Only console saved me (Ctrl-Alt-F1).
I noticed the same info about Gdkpixbuf loader module in the bug description. Also gdk-pixbuf-query-loaders was not installed. But I just did not worry about these messages. On next boot the problem aroused. I analysed apt log file and isolated last two dist-upgrades (below). I decided to downgrade the first ones and I regained login to desktop.

But at least I can work.

Then I started Synaptic, and oops! no GUI, only the borders of the window would show. Several other programs were affected and would not start (Geany, text editor), or show their content. After tests and research it appeared only GTK3 programs were affected. If using a theme with GTK2, or move the GTK configuration out of the way, the programs would work. The upgrade contained the following packages: gir1.2-gdkpixbuf-2.0_2.30.7 libgdk-pixbuf2.0-0_2.30.7 libgdk-pixbuf2.0-common_2.30.7 I fixed the issue by booting to the Live USB I had used to install, and repackage the programs with dpkg-repack, then reinstalled them using "sudo dpkg -i *.deb". (copied from the live usb to the home in the install, rebooted and reinstalled there). Problem solved for this install, where I have for now blocked the update for these three packages. At post-install, after I had updated, I had the same message as the people who reported that bug: https://bugs.launchpad.net/ubuntu/+source/gdk-pixbuf/+bug/1282294 **** (gtk-update-icon-cache-3.0:29671): GdkPixbuf-WARNING **: Cannot open pixbuf loader module file '/usr/lib/x86_64-linux-gnu/gdk-pixbuf-2.0/2.10.0/loaders.cache': No such file or directory This likely means that your installation is broken. Try running the command gdk-pixbuf-query-loaders > /usr/lib/x86_64-linux-gnu/gdk-pixbuf-2.0/2.10.0/loaders.cache to make things work again for the time being. **** and when trying to do so, the console returned a message stating gdk- pixbuf-query-loaders was not installed. (no such package in the repos either). More information can be found at http://irclogs.ubuntu.com/2015/09/06/%23ubuntu-bugs.html where I discussed about this bug and my findings. Now I will try to produce this bug again in the Live USB (which has no persistence).
