Open a file with 9 sheets (one with a graph). The file has links with others
files but there is no message asking for update. When changing of sheet, on a
sheet there is an error message box: 
"**Error**:file shape.c:line75(pango_shape):assertion failed:
(glyphs->num_glyphs>0)aborting...
In the window opened when starting Gnumeric, there are warnings appearing during
the start up about two keys with double links (french langage). After the error
message box, there are 2 messages:
**<gnumeric.exe>: Glib-GObject-CRITICAL **file gobject.c:line 1561
<g_object_ref>: assertion 'G_IS_Object <object>' failed
**<gnumeric.exe>: CRITICAL ** file pango-engine.c: line 68
<_pango_engine_shape_shape>: assertion 'PANGO_IS_FONT <font>' failed.
The file is ok under Excell 97 and 2000; OOO can open but cannot draw a graph
with curves and bars. Gnumeric displays correctly the graph.
