The analytic_multicurrency module, (trunk version as made available from the OpenERP site) references a configuration key 'price_accuracy', which according to openobject-server bug #671748 (see https://bugs.launchpad.net/openobject-server/+bug/671748 for details) was deprecated in OpenERP 6.0.
The following stack trace is emitted when installing the module.
