goocanvas.Table: segfaults adding group

[Alessandro Dentella <sandro e-den it>]

Hi,

can I add a group as child in a table? the attached code (derived from the
demo) works if I add rectangles and segfaults on Ubuntu 8.04 if I add
groups:

The difference is shown below.
This works:

   def create_rect (table, row, column, text, width=None):
       item = goocanvas.Rect (parent = table,
				  width = width or 38,
				  height = 19,
				  fill_color = "red")

       table.set_child_properties (item, 
				   row = row,
				   column = column,)



This segfaults on ubuntu 8.04 gocanvas 0.9 (but works on ubuntu 9.04
goocanvas 0.10):

   def create_group (table, row, column, text, width=None):
       gr = goocanvas.Group(parent=table)
       item = goocanvas.Rect (parent = gr,
				  width = width or 38,
				  height = 19,
				  fill_color = "red")

       table.set_child_properties (gr, 
				   row = row,
				   column = column,)
