AttributeError: 'NoneType' object has no attribute 'days'

How to Reproduce

While doing a GET operation on /ticketcalendar-box, Trac issued an internal error.

I've installed agile from the egg package available at ​http://www.agilofortrac.com/en/download/licensed/binary_agilo-PRO-py2.7.egg.zip, in a Ubuntu Server 12.04 host. Then, I've installed the TicketCalendar Plugin from the zip file available at ​http://trac-hacks.org/changeset/latest/ticketcalendarplugin?old_path=/&filename=ticketcalendarplugin&format=zip. I compiled and then used easy_install to install the egg package. I also run sudo trac-admin $ENV upgrade, and set up the plugin options in trac.ini ticketcalendar.* = enabled and ticketcalendar.web_ui.ticketcalendarmodule = enabled. After that when I access the link ​http://HOST/agile/ticketcalendar-box or click the corresponding button in the panel, the following error message appears AttributeError: 'NoneType' object has no attribute 'days'. How can I fix it?

Thanks for your reporting! Reproduced using Trac with no message catalogs to install Babel after Trac.

In 13398:

ticketcalendar: fixed AttributeError exceptions if Trac has no message catalogs and Babel is installed (refs #11328)
