Bug in pango_layout_index_to_pos()

[Oisin Boydell <Oisin Boydell Sun COM>]

I noticed a bug in the function pango_layout_index_to_pos() which takes 3 
parameters, a PangoLayout*, a gint index and a PangoRectangle* which is an 
in/out parameter.
The PangoLayout that I give this function belongs to a GtkEntry object, but I 
find that the GtkObject fails the ATK_IS_OBJECT assertion after using the 
function. This indicates that the pango_layout_index_to_pos() function corrupts 
the object/structure whose PangoLayout I pass in to the function. This is also 
the case when passing the function a PangoLayout which is part of a GtkLabel 
object.
I have looked at the code for the pango_layout_index_to_pos() but I can see  
nothing obvious, so I suspect that the problem could be with one of the pango 
functions that pango_layout_index_to_pos() calls internally.

Has anybody else noticed this problem?

I have submitted this as a bug in Bugzilla #57391
