They work, but they are not relevant to this problem. Darren has
confused the issue by applying a fix to backend_gtkcairo.py (with no
CHANGELOG comment) while you and I are investigating the problem. So we
are executing the workaround command and are unable to reproduce the
bug.
However, if I put the line
import matplotlib.backends.backend_cairo as be_cairo
back into backend_gtkcairo.py I can now see the problem.
