[Python-modules-team] Bug#477953: python-enthought-chaco2: Example fails to run

[Y. Wei]

Package: python-enthought-chaco2
Version: 2.0.4-2
Severity: normal


One example in the examples/chaco2 fails to run and complains about font
initialization. I am actually running python2.5 as the default python but
reportbug list python2.4.

~$ python scales_test.py
