There's a conflict between your maemo abiword and the debian abiword. In particular, debian abiword icon tries to overwrite maemo abiword's one.
If you don't need maemo abiword (and you won't need it after installing debian abiword, because the maemo port isn't stable and finished as the debian one) just uninstall that one through the application manager before installing easy debian.
Otherwise, if you want to have both, you could (as root), delete /usr/share/icons/hicolor/scalable/hildon/abiword.png before installing easy debian.
