Message extraction fails with Trac 1.4

[Ryan J Ollos]

I ran into this issue while trying to solve #14056:

$ python setup.py extract_messages

extracting messages from tracdragdrop/web_ui.py
extracting messages from tracdragdrop/templates/genshi/tracdragdrop.html

Thanks for the reporting! I had never extracted messages after supporting the Jinja2 template....
