Errors in the Help for QDeclarativeEngine

There is a string "Returns the provider if it was found; otherwise returns 0" in the documentation for void QDeclarativeEngine:: removeImageProvider (const QString & providerId), but the function returns void.
The implementation of this function uses d-> imageProviders.take (providerId), although in this case it is better to use the remove method.
The documentation does not indicate that QDeclarativeEngine takes care of removing added QDeclarativeImageProvider.
