Some awkward bugs in the 1.3.0, so hot on its heels is 1.3.1:
* Fixed traceback due to libsane-hpaio installation check.
* Removed duplicate method definition.
* Defer calls to populateList initiated by monitor.
* firewall: fixed cache behaviour.
* Fixed page sequence when adding a printer with an exactly-matching
driver.
