[gcompris-devel] gcompris and gnome 2.2

[bruno]

Welcome olivier, I re-tell here what we said at the Fosdem. 

I see a demand in being able to develop python activities in gcompris.
This was in the TODO of my slides (my slides are in the file
architecture.sxi on the gcompris web site).

Olivier proposed to implement the python bindings in gcompris which I
hope could boost boards creations.

Now for the bug you have, I prefer to wait and/or submitting bugs to
gnome instead of patching gcompris. Also I have not seen the problem on
mainstream distribution and nobody else reported that.
What is you libgnomecanvas version, on my side I have:
rpm -qa | grep canvas
libgdk-pixbuf-gnomecanvas1-0.18.0-3mdk
libgnomecanvas2_0-devel-2.0.2-1mdk
libgnomecanvas2_0-2.0.2-1mdk

Bruno.
