I just trying to generate a compass image sprite with assetic in symfony 2.2 project. I configured compass filter and i have some .scss files working perfect. But when I try to generate an image sprite and run ./app/console assetic:dump --watch throw an error:
[error] An error occurred while running:
'/usr/bin/ruby' '/usr/local/bin/compass' 'compile' '/tmp' '--images-dir' '/home/xuser/desarrollo/www/lab.dev/symfony/app/../web/images' '--config' '/tmp/assetic_compass5atwLN' '--sass-dir' '' '--css-dir' '' '/tmp/assetic_compassiAf1jw.scss'
Error Output:

I note the sprite is generated fine, but copied in /tmp/images/. I currently I do the same thing in a stand alone compass project and work fine, the issue is throug assetic. Could you help me?
