* I've got this error:
<pre>
  src/CommitDialog.cpp:58:49: error: invalid use of incomplete type ‘class QAction’
    QAction* action = new QAction(ui->plainTextEdit);
</pre>
* This is my system configuration:

  src/MainWindow.h:

  #include <QMainWindow>
#include <QStringList>
#include <QFileIconProvider>
+ #include <QAction>
#include "AppSettings.h"
#include "Workspace.h"
