This is probably the same problem I described a couple of days ago on this list.
The Gtk+ bugreport is here: https://bugzilla.gnome.org/show_bug.cgi?id=628291
You could wait till a patch lands in gtk 2.22 or apply one of the
patches attached to the bugreport and build gtk yourself, both patches
solve the problem.

You don't have to use all the git versions to get it running. For
example the latest released version of Poppler 0.14 and libpng14 works
fine too. I usually get the packages I don't want to compile myself
from the BuildService.
