* debian/control: Build with libpodofo-dev to enable PDF metadata.
  (Closes: #619632)
* debian/control: Add libboost1.42-dev build dependency. Apparently it is
  needed in some setups. (Closes: #619807)
* debian/rules: Call dh_sip to generate a proper sip API dependency, to
  prevent crashes like #616372 for partial upgrades.
* debian/control: Bump python-qt4 dependency to >= 4.8.3-2, which reportedly
  fixes crashes on startup. (Closes: #619701, #620125)
