[viewvc-dev] Bug with viewsvn template and version 1.1.13

I've been migrating a ViewVC installation that in the past used:

  template_dir = templates-contrib/viewsvn/templates

to a newer Linux distro, Python and Apache version and upgraded ViewVC in the process. Ever since, I received the following error when trying to look at CVS repos (but not SVN repos, which continued to work fine):

--------------------------

After some tinkering, I figured I should try to get my configuration back to the default as much as possible and started by what I suspected to be the problem (considering ezt.py being the "cause"): the templates.

So I commented out my template_dir line and lo and behold, it started to work again for both CVS _and_ SVN repos. So for now I'll leave it at that, but I presume there is an error in the template and I'll try to make some time to track it down and send a patch.
