Upon further inspection this may be an issue with the libraries themselves not loading the correct binaries *(I'm not sure how that trickle down loading all works).  

Here's my ldd output for agnclient.  Conspicuously absent is a line for libpixbufloader-png.so.  and libpixbufloader-svg.so which leads me to believe they are attempting to be loaded by  /usr/lib32/libgtk-x11-2.0.so.0.  However when doing an ldd on that library *(following the ldd for agnclient), it points to all the correct libraries.
