Error: Invalid value for argument 2. Property 'toolbar': Unexpected property.

Hey guys,

I installed Koala a few minutes ago and tried to compile my scss styles.
But then I got this error.

---uncaughtException---
Error: Invalid value for argument 2. Property 'toolbar': Unexpected property.

Maybe there is a problem with the SassCompiler.js? But If I specify the sass compiler by myself then it's not working, too.

gem install sass
sass -v
Sass 3.4.23 (Selective Steve)
