Programs that include kdirselectdialog.h will not compile unless qpopupmenu.h is explicitly included (eg kdirselectdialog.cpp).

kdirselectdialog.h requires qpopupmenu.h since QPopupMenu is referenced in line 112.

105:private:
106:    void readConfig( KConfig *config, const QString& group );
107:    void saveConfig( KConfig *config, const QString& group );
108:    void openNextDir( KFileTreeViewItem *parent );
109:    KFileTreeBranch * createBranch( const KURL& url );
110:
111:    KFileTreeView *m_treeView;
112:    QPopupMenu *m_contextMenu;
113:    KToggleAction *m_showHiddenFolders;
114:    bool m_localOnly;

Would it not make more sense to #include <qpopupmenu.h> in this header file? Otherwise programs such as kdebingings/kdejava/koala/kdejava/KDirSelectDialog.cpp MUST include qpopupmenu or else it won't compile.
