+Summary: create_row_drag_icon and custom cell renderer problem
+
+(I'm not 100% sure if this is a gtkmm problem or a gtk+ API issue)
+ 
+I'm experimenting with a custom cell renderer derived from
+CellRendererText which has its own render_vfunc() method, which works
+fine when drawing normal rows.
+ 
+I'm also using drag & drop with a custom cursor using the
+create_row_drag_icon() method. The problem is that render_vfunc() has a
+refptr to a Window as its first argument, where as the
+create_row_drag_icon() method invokes the cell renderer vfunc with a
+Drawable.
+
+Because the drawable is wrapped in a RefPtr<GtkWindowObject>, the
+creation of this ref pointer fails (it tries to do a <dynamic_cast> from
+the drawable to a window object, so we get a null pointer) and an
+invalid window reference results.
+
+Is this a problem in the gtk+ definition (which also has a Window as its
+argument, not a Drawable, but of course doesn't have the dynamic cast
+problem) or in the gtkmm wrapper of the cellrender API, or is there
+something else I'm missing ?
+
+I will upload a test program which tickles this problem. It's a bit long
+due to all the view setup code.
