Similar problem with tabbed property sheet and common navigator. 
We have also created a custom common navigator and enabled the use of a tabbed
property sheet extension.

It worked fine in 3.4.x, but when using 3.6.0 the tabbed property sheet failed
to load. Traced to the code below:

public class TabbedPropertySheetAdapterFactory
    implements IAdapterFactory {

    /*
     * (non-Javadoc)
     * 
     * @see
org.eclipse.core.runtime.IAdapterFactory#getAdapter(java.lang.Object,
     *      java.lang.Class)
     */
    public Object getAdapter(Object adaptableObject, Class adapterType) {
        if (adaptableObject instanceof ProjectExplorer) {
            if (IPropertySheetPage.class == adapterType)
                return new TabbedPropertySheetPage(
                    new TabbedPropertySheetProjectExplorerContributor(
                        (CommonNavigator) adaptableObject));
        }
        return null;
    }

The #getAdapter() will always return null for my CommonNavigator.
