gcompris crash in gnome-canvas-pixbuf.c

[Bruno Coudoin <bcoudoin anfora fr>]

Hi,
I am the author of gcompris (http://gcompris.sourceforge.net) and I have
a major stability issue. Gcompris crashes randomly after
entering/exiting around 10 times any board.
GCompris uses gnome and specificaly the canvas with the pixbuf image
manipulation program.
After recompiling gdk-pixbuf-0.11.0 and installing it on my box, I can
trace the crash up to gnome-canvas-pixbuf.c as seen in the following
trace.
I am perhaps doing something wrong in gcompris but can't find what.
Can somebody help me with that ?

Thanks in advance,
Bruno.
