ignore_paths causing error

[halcarleton]

When I try to exclude files using ignore_paths I get this error:

(erb):1:in `get_binding': undefined local variable or method `rendered_example' for #<Hologram::TemplateVariables:0x000000011c71d0> (NameError)

I have not edited any of the included templates/assets and am not using any custom renderers. When I remove ignore_paths from the config it works fine.

Here's my files

Config

source: ./public
ignore_paths:
  - "*.scss"
destination: ./public/styleguide
documentation_assets: ./public/_doc_assets
code_example_templates: ./public/_code_example_templates
index: basics
nav_level: all
exit_on_warnings: false

CSS

(I replaced the backticks with single quotes because I couldn't figure out how to escape them)

/*doc

title: Buttons
name: button
category: Basics

Button styles can be applied to any element. Typically you'll want
to use either a `<button>` or an `<a>` element:

'''html_example
<button class="btn">Click</button> <a
class="btn" href="#">Click</a>
'''

.btn {
  display: inline-block;
  background: #bada55;
  border: 4px solid #383838;
  padding: 1em; }
