This bug was fixed in the package at-spi2-atk - 2.4.0-1ubuntu2

---------------
at-spi2-atk (2.4.0-1ubuntu2) precise; urgency=low

  * debian/control:
    - Demote libatk-adaptor-schemas dependency to recommends
    - libatk-adaptor-schemas should depend on libatk-adaptor, so that
      libatk-adaptor gets installed first, thus preventing file conflict
      issues on upgrade from oneiric. (LP: #973740)
