InstallationIssue.

You've installed a customized ticket_notify_email.txt in /var/data/trac/templates, however the template file is probably a Genshi template or wrong Jinja2 template. Trac 1.4 switched from Genshi to Jinja2 template engine.

You should correct the template file.

Looks like we might need to update the example in the documentation: 1.3/TracNotification. And also mention the need to adapt Email templates in 1.3/TracUpgrade.
