Known problems fixed in GtkAda 1.2.12/1.3.12

- SEGV in Gtk.Extra.PsFont.Get_Gdkfont when no font is found
  Problem:    When Get_Gdkfont is called (either directly on indirectly),
              a chunk of memory is deallocated twice when no font can be found
              on the system.
  Workaround: No simple work around. The problem will only occur in rare cases
              when the fonts cannot be found.

- Selecting a non-existent file in Gtkada.File_Selection generates a CE
  Problem:    When entering a non-existent file in Gtkada.File_Selection
              with the option Must_Exist set to True, File_Selection_Dialog
              raises a Constraint_Error.
  Workaround: Add a handler for Constraint_Error around the call to
              File_Selection_Dialog.

- Gtk.Label.Parse_Uline Does not return a Gdk_Key_Type
  Problem:    Parse_Uline does not return a Gdk_Key_Type as the underlying C
              function, so installing accelerators by hand is not possible.
  Workaround: Import gtk_label_parse_uline directly.

- Gtk.Ctree.Free_Data does not free memory
  Problem:    Free_Data is a no-op.
  Workaround: Unse Unchecked_Deallocation on the Data directly.

- Gnome.*.Initialize do not properly initialize the widget
  Problem:    Most Gnome.*.Initialize procedures fail to initialize the
              internal user data associated with each widget.
  Workaround: Call Initialize_User_Data (Widget) manually after each call to
              Gtk_New/Initialize.

- Declaring new signals for widgets with a common parent
  Problem:    When declaring new signals (with Initialize_Class_Record) for
              two widget types that extend the same Gtk parent, the first one
              is not taken into account and the signal is not accessible.
  Workaround: Declare a first child of the Gtk parent, and make the two other
              widgets inherit from it. Declare the signals for this first
              child.

- Option menus not shown properly when using the GUI builder
  Problem:    When creating option menus using the GUI builder, gate would
              not generate a code that would display the option menu items
              by default.
  Workaround: Modify the generated code by hand, adding explicitely calls
              to Show (The_Menu_Item).

- Callbacks with same name not handled correctly by Gate
  Problem:    Callbacks with the same name in different top level widgets
              in the XML file were not duplicated in each callbacks package.
  Workaround: Use unique name among the project, or modify the generated code
              by hand.

- Connecting signals with Object_Connect might raise CE later on
  Problem:    When you connect a signal to object A with object_connect,
              passign object B as the slot object, it might happen than B
              is destroyed but not A. The next time the signal is emitted, you
              will get a Constraint_Error, since B no longer exists
  Workaround: Connect the "destroy" event to object B, so as to automatically
              disconnect the first signal when B is destroyed. This is now
              done automatically by GtkAda
