Upgrading to the Squeeze version of Abiword did not work for me. It complained about the absence of libgoffice-0.8.so.7 .

I finally created a symlink with that name in /usr/lib (in the debian file system) and linked it to libgoffice-0.8.so.8.0.0 in the same directory. Abiword now starts as it should, but I can't yet verify that everything works correctly.
