ruby on rails - Cloudinary Gem Breaking Bootstrap on Heroku -

i have rails app has photo uploading feature. using carrierwave_direct upload directly s3 (based on railscast 383). in order optimize app, went ahead , switched cloudinary.

the app works locally fine cloudinary. when pushed heroku app crashes server log error:

actionview::template::error (invalid css after "  font-family: ": expected expression (e.g. 1px, bold), "@altfontfamily;" 2013-09-04t05:16:29.148898+00:00 app[web.1]:   (in /app/app/assets/stylesheets/application.css)): 2013-09-04t05:16:29.148898+00:00 app[web.1]:     12:       <script src="//cdnjs.cloudflare.com/ajax/libs/html5shiv/3.6.1/html5shiv.js" type="text/javascript"></script> 2013-09-04t05:16:29.148898+00:00 app[web.1]:     13:     <![endif]--> 2013-09-04t05:16:29.148898+00:00 app[web.1]:     14:  2013-09-04t05:16:29.148898+00:00 app[web.1]:     15:     <%= stylesheet_link_tag "application", :media => "all" %> 2013-09-04t05:16:29.148898+00:00 app[web.1]:     16:  2013-09-04t05:16:29.148898+00:00 app[web.1]:     17:     <!-- third-generation ipad high-resolution retina display: --> 2013-09-04t05:16:29.148898+00:00 app[web.1]:     18:     <!-- size should 144 x 144 pixels --> 2013-09-04t05:16:29.149145+00:00 app[web.1]:   app/views/layouts/application.html.erb:15:in `_app_views_layouts_application_html_erb__164934612574999860_69925614481940' 2013-09-04t05:16:29.149145+00:00 app[web.1]:  2013-09-04t05:16:29.149145+00:00 app[web.1]:  2013-09-04t05:16:29.149499+00:00 app[web.1]: processing landingcontroller#landing html 2013-09-04t05:16:29.149499+00:00 app[web.1]:   rendered landing/landing.html.erb within layouts/application (58.3ms) 2013-09-04t05:16:29.149499+00:00 app[web.1]: completed 500 internal server error in 158ms 

i reverted previous commit previous adding cloudinary (when app worked, , have isolated moment when app starts breaking when add cloudinary gem. though error references css error app breaks when add cloudinary gem.

in process of trying figure out discovered when run heroku run rake error.

rake aborted! undefined method `[]' nil:nilclass

i suspect issue, app breaks when adding cloudinary gem, though if run 'heroku run rake' before adding gem, same error, yet app still functions.

here got when ran heroku run rake --trace
