/usr/lib/libglade should be /usr/lib/x86_64-linux-gnu/libglade on 64 bit multiarch

Precise; May also affect Oneiric.

GnuCash won't work properly right now. In /tmp/gnucash.trace, I find this:

* 12:59:44 WARN <libglade> Could not load support for `gnome': libgnome.so: cannot open shared object file: No such file or directory
* 12:59:44 WARN <libglade> unknown widget class 'GnomeDruid'
* 12:59:44 WARN <GLib-GObject> invalid cast from `GtkLabel' to `GnomeDruid'
* 12:59:44 WARN <GLib-GObject> invalid cast from `GtkLabel' to `GtkContainer'

Running GnuCash under strace shows this:

cd /usr/lib/x86-64-linux-gnu
sudo ln -s ../libglade .

... causes is to run flawlessly. Therefore, I conclude that the libraries that libglade2-0 are looking for don't belong in /usr/lib/libglade anymore, but in /usr/lib/x86-64-linux-gnu/libglade instead. That includes libbonoboui2-0, libgnomeui-0, libgnomecanvas2-0 (that I know of).
