NoMethodError: undefined method `read' for "css/path/to/file.css":String

Hi, I'm getting an error (like I wrote in title) while trying to use sass-convert on a directory containing css files.

Backtrace:

(Moving my comment to a new issue #1835 since I no longer think it's the same problem.)

Thank you for reporting this issue, but it's hard to know how to reproduce it based on your description. Please include steps to reproduce this.

@chriseppstein There's really not many steps to reproduce this. My environment is Mac OSX.

Once SASS is installed:

If I include the backtrace, it looks just like what @wildpine posted

How do I get/run the fixed version? I just got the latest versions of Sass and Compass for Windows, and the bug fix isn't there:
gem uninstall compass
gem uninstall sass
gem install sass -v 4.0.0.alpha.1
gem install compass -v 1.1.0.alpha.3
gem clean
sass-convert -R C:\Users\phayes\css_to_scss --from css --to scss --trace
sass_convert.rb:246:in block in process_file': undefined methodread' for "C:/Users/phayes/css_to_scss/style-legacy.css":String (NoMethodError)
