I have just got this error on a Xubuntu 14.04 system when I did an "apt-get dist-upgrade" on it.
I'm very careful to make sure that old settings files are purged when packages are removed, so I'm pretty sure that there were no residual configuration files remaining when I installed the updates. I even ran an "aptitude purge '?config-files'" first, just to be sure.

Also, I had double-checked that there were no 'automatically installed packages that are no longer needed' present on the system ("apt-get --purge autoremove" did nothing), so I was safe there, too.

The first visual clue that indicated that the problem was real, was the Mousepad file selection dialog, which didn't work; there was no file list and no buttons on the dialog windows, but just a grey background instead. After a reboot, the desktop background, the icons, and all kinds of visual elements were messed up.

I then did what the error message suggested, i.e.:
gdk-pixbuf-query-loaders > /usr/lib/x86_64-linux-gnu/gdk-pixbuf-2.0/2.10.0/loaders.cache

That told me that "gdk-pixbuf-query-loaders" was not installed, and wanted me to run the following:
apt-get install libgdk-pixbuf2.0-dev

I then reran the "gdk-pixbuf-query-loaders" command, and rebooted. After that, all was well again.

I then did an "apt-get dist-upgrade" on another Xubuntu 14.04 system, and that didn't run into any problems.

The two systems had initially been freshly installed (no update from an earlier release). The one that presented the problem had not been updated for quite a while (one and a half to two months, I believe), while the other one, with no problems, gets updated at least once a week. Also, the problematic system does not have the xubuntu-restricted-extras installed, while the second one does (though I doubt it that this will be the cause of the issue). The problem system was installed more recently, from the 14.04.2 release, while the other one was installed from the initial 14.04 release.
