1. Create a Qt Widgets Applications project.
2. In Projects view, right-click the project's root node and select "Add New..." from the context menu.
3. Add a C++-class derived from Q_Object.
4. Add the line

   Q_PROPERTY(QString foo READ foo WRITE setFoo NOTIFY fooChanged)
   

5. Place your cursor at the end of that line and press Alt+Enter.
6. Press Enter.
   The inserted code is indented incorrectly.
7. Remove the inserted code.
8. Remove the Q_OBJECT macro from the class.
9. Repeat steps 5 and 6.
   The inserted code is indented correctly.

Automatically generated code should always be indented correctly. Maybe this is related to QTCREATORBUG-11413 although I can't reproduce that one in 3.3.
