UIDeviceRGBColor leak - how to fix?

问题

I am using the three20 library (not sure if this is the cause) and am getting a leak when going back and forth between two views of a navigation controller.

More details of one of the leaks:

The only think I can think of is that I show the toolbar when it pushes the second view onto the stack:

/**
 * View is going to appear
 *
 * @version $Revision: 0.1
 */
- (void) viewWillAppear:(BOOL)animated {
    [self.navigationController setToolbarHidden:NO animated:animated];
    [super viewWillAppear:animated];
}//end


/**
 * View will disappear
 *
 * @version $Revision: 0.1
 */
- (void) viewWillDisappear:(BOOL)animated {
    [self.navigationController setToolbarHidden:YES animated:animated];
    [super viewWillDisappear:animated];
}//end

For the life of me, I cannot figure out where this is coming from. The extended detail stack trace is not showing any of my classes.

Where could this be coming from?

If you are customizing the navbar tint color, or any other colors, in one of the three20 stylesheets, make sure you are returning an autoreleased color.
