I am always tempted to blame my code, but the same problem appeared
in the Ambulant demo wrapper (player_pygtk.py) on Ubuntu. It appears
only in the python wrapper (not the C++ version). The Ambulant team has
opened a ticket. The problem appears to be an interaction between the
gtk.main() event loop and the Ambulant redraw logic. Player_pygtk.py
doesn't call gtk.main but instead uses a loop:
I think it is safe to rule out Sugar as a culprit, but not my building
of the Ambulant package!
