Crash in qml/installer test

PASS   : appman-qmltestrunner::tst_installer.qml::Installer::initTestCase()
QWARN  : appman-qmltestrunner::tst_installer.qml::Installer::test_1states() QDBusMarshaller: type `QtAM::Package*' (1030) is not registered with D-BUS. Use qDBusRegisterMetaType to register it
dbus[14186]: Array or variant type requires that type variant be written, but end_dict_entry was written.
The overall signature expected here was 'sa{sv}' and we are on byte 4 of that signature.
  D-Bus not built with -rdynamic so unable to print a backtrace
