After some more searching I see that there are some related threads in the developer forums and this issue has been noted for some time. I expect I will receive response that my bug report is a dupe. In the meantime, I believe I have come up with a workaround.

What I came up with is a sequence of setting

self.navigationController.navigationBar.translucent = NO;
self.tabBarController.tabBar.translucent = NO;

when the view containing a MKMapView is loaded and then setting it YES in viewDidAppear. I set to NO again on viewWillDisappear. Then the returning viewController must reset to translucent again in its viewDidAppear.

I used a series of NSNotification posts in the View Controllers with the maps. I subclassed my navigation controllers and tab bar to make them listen for the notification and respond by toggling their own bar translucency property.

Managed to get it done. With a small amount of code, but it is an awful lot of activity for no good reason. Would more like to see this fixed ASAP.
