[Buildbot-devel] regression causing build pages to explode with "<class 'jinja2.exceptions.TemplateSyntaxError'>: Encountered unknown tag 'endif'. Jinja was looking for the following tags: 'endmacro'. The innermost block that needs to be closed is 'macro'."

[Dan Kegel]

I use buildbot from git, and a fresh checkout just now explodes when
I try to look at a build page.
http://localhost:8010/builders/runtests-default/builds/0 has lots of
errors, but none of them seem really clear offhand:

web.Server Traceback (most recent call last):
<class 'jinja2.exceptions.TemplateSyntaxError'>: Encountered unknown
tag 'endif'. Jinja was looking for the following tags: 'endmacro'. The
innermost block that needs to be closed is 'macro'.
