QtLocation Map performance issue with copyright info

It seems that QGeoTiledMapNokia::evaluateCopyrights is taking around 600 ms off our app's startup time. copyrightsVisible is set to false, yet this is still going into all sorts of computationally intensive font/text related call stacks.

It seems that even when copyrightsVisible is false, all the info is still fetched and rendered anyways, just not displayed at the last minute. If this copyrightsVisible property is false, fetching the info should not even be attempted, in order to improve performance.
