qnetworksession.h Q_DECLARE_METATYPE breaks building QtMobility QtBearer depening applications

There is an addition to the header qnetworksession.h for metatype declarations.

Q_DECLARE_METATYPE(QNetworkSession::State)
Q_DECLARE_METATYPE(QNetworkSession::SessionError)

The declarations do not resolve correctly when QT_MOBILITY_BEARER is defined, because QtMobility classes have default namespace set.

Suggested solution is either flag out the namespace declaration from the QtMobility path of the header or do separate declarations for both. The latter would mean that update would be needed to QtMobility QtBearer header as well to keep the header content align.
