Error testing thrown exceptions in Spock unit tests

When I try to test for a thrown exception using the following code: 

@TestFor(EncryptionService)
class EncryptionServiceSpec extends Specification {
def "test decryption of unecnrypted file"(){
    setup: 
        def clearTextFile = new File("test/resources/clearText.txt")
        clearTextFile.write("THIS IS CLEAR TEXT")

    when:
        def (privateKey,publicCert) = service.generateKeyPair("123")
        service.decryptFile(new FileInputStream(clearTextFile), privateKey )

    then:
        clearTextFile.delete()
        thrown GeneralSecurityException
}
}

I get the following compilation exception when I run either grails test-app -unit

Unexpected error during compilation of spec 'com.genospace.services.EncryptionServiceSpec'. Maybe you have used invalid Spock syntax? Anyway, please file a bug report at http://issues.spockframework.org.

java.lang.ClassCastException: org.codehaus.groovy.ast.expr.ArgumentListExpression cannot be cast to org.codehaus.groovy.ast.expr.VariableExpression at org.codehaus.groovy.ast.expr.DeclarationExpression.getVariableExpression(DeclarationExpression.java:103) at org.spockframework.compiler.SpecRewriter.moveVariableDeclarations(SpecRewriter.java:538)

Try without leveraging Groovy's multi-assignment feature (def (privateKey,publicCert) = ...). If this solves the problem (and I think it will), please file an issue at http://issues.spockframework.org.
