+> - Is this a bug?
+
+First test case: no: use of gtk(mm) functions (here for setting up
+custom GValue type) before instantiating Gtk::Main is not allowed.
+
+Second test case: not really: use of custom GValue types is perfectly
+legal. However it is not possible to automatically create a
+TreeViewColumn from TreeView::append_column(). Instead, the
+TreeViewColumn has to be created manually and a function for
+displaying data has to be provided with
+TreeViewColumn::set_cell_data_func(). After that, the column can be
+appended directly with the appropriate TreeView::append_column() overload.
+
+
+> - Otherwise: Why not? Can error messages be triggered at compile time?
+
+First test case: No.
+
+Second test case: In theory. The TreeView::append_column(const
+Glib::ustring& title, const TreeModelColumn<ColumnType>& model_column)
+overload should fail if the TreeModelColumn uses a custom GValue type.
+A compile-time-check can be added using some template magic with
+template specializations for all supported types. The corresponding
+TreeView::append_column_editable() overload already fails to compile
+if the type is not supported. A run-time-check might be easier and
+cleaner to implement (somehow check Value<the_type>::value_type()).
+
+
+> - Otherwise: Where shall we document this behaviour?
+
+First test case: Already documented in
+file:///usr/local/share/doc/gtkmm-2.0/docs/reference/html/classGtk_1_1TreeModelColumnRecord.html
+
+Second test case:
+file:///usr/local/share/doc/gtkmm-2.0/docs/tutorial/html/ch08s02.html#id2962983
+and
+file:///usr/local/share/doc/gtkmm-2.0/docs/reference/html/classGtk_1_1TreeView.html#a25
+should mention that TreeViewModelColumns that use custom GValue types
+can not be used this way. The standard GValue types have to be listed
+somewhere.

+The only problem I see after improving the documentation of
+TreeView::append_column is that I find it quite difficult to track
+down the runtime error
+
+(a.out:1163): GLib-GObject-WARNING **: unable to set property `text'

+to an incorrect use of this function. Maybe we should cite the error

+Sorry, was moving. No, it's not the same patch. It's the latest patch
