Cannot create new gradle project in Idea 13 Beta Follow

When I try to create a new gradle project using the wizard I always get the following error:

"Gradle 'helloworld' project refresh failed:
            Could not initialize class org.gradle.internal.nativeplatform.filesystem.FileSystems$DefaultFileSystem"

What am I doing wrong here? I already tried several times, I also tried to use a local installation of gradle instead of the wrapper. In both cases (wrapper or local install) I get the same error.

My environment:

• Idea IU-132.947
• Ubuntu 13.10 (32 Bit)
  
• Oracle Java 1.7 Update 45.
