I found a workaround, and committed it. I don't understand what the root of
the problem was, probably because the AttributeError at the end of the
Traceback is misleading. Changing this:
import matplotlib.backends.backend_cario as be_cairo
to this:
from matplotlib.backends import backend_cairo
and updating references to be_cairo was all that was needed. The fix is in svn
2979.
