Comment 1 for bug 202448

It appears related to this bug http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=464350 ,but for some reason 2.1 works for me while 2.2 doesn't. Simple GTK apps such as dopewars, euler (run from extracted 32 bit deb packages) don't load at all, showing

(dopewars:13381): GdkPixbuf-WARNING **: Error loading XPM image loader: Unable to load image-loading module: /usr/lib/gtk-2.0/2.10.0/loaders/libpixbufloader-xpm.so: /usr/lib/gtk-2.0/2.10.0/loaders/libpixbufloader-xpm.so: wrong ELF class: ELFCLASS64

regardless of the environment variables set.

Here are the last few lines ltraced from running dopewars

Unfortunately it seems difficult to run ltrace on firefox and acroread due to the myriads of launcher scripts and dlopened components.
