 For missing layer the QgsMapLayer::readXML failed (because the data
 provider
 fails to initialize) and the layers aren't added to the map layer
 registry:

 http://trac.osgeo.org/qgis/browser/trunk/qgis/src/core/qgsproject.cpp#L715

 All such layer nodes are collected and later passed to

 http://trac.osgeo.org/qgis/browser/trunk/qgis/src/gui/qgsprojectbadlayerguihandler.cpp#L16

 which tries to update the datasource and reread the bad layer node.
