[Trac] Jina2 2.11.0 on Trac 1.4: "the inline if-expression on line 109 in 'theme.html' evaluated to false and no else section was defined"
Hi all,
I'm working on creating a fresh up-to-date Trac install recipe for my
department, and I encountered an exception with Jinja2 2.11.0 under Trac
1.4. I wanted to run this problem by the list before logging a ticket.
Ubuntu 18.04
Python 2.7.17 virtualenv
Installing newest version of all prerequisites with pip
When I run the server via tracd, the main page displays correctly, but when
I click Timeline, Roadmap, View Tickets, or Search, only part of the page
source is returned (nothing renderable by the browser) and an exception
appears in the trac.log:
2020-01-29 16:22:41,020 Trac[chrome] ERROR: Jinja2 UndefinedError error

for piece in template.split("/"):
UndefinedError: the inline if-expression on line 109 in 'theme.html'
evaluated to false and no else section was defined.
When I pin Jinja2 to 2.10.3, the problem goes away. So, it seems like
changes to Jinja2 from 2.10 to 2.11 cause this breakage.
Anyone else seen this?
All the best,
Chuck Bearden
