I faced the same problem and I could solve it by changing the version of chunky_png to 1.3.6:

gem uninstall chunky_png --version 1.3.8
gem install chunky_png -v 1.3.6

Here an overview of the versions of related packages (which works for me):

• sass (3.4.22)
• chunky_png (1.3.6)
• compass (1.0.3)

You can check your versions with:

gem list
