IllegalArgumentException on Indexing

I get an error when i load my Symfony Controller Files. It marks some lines yellow but there aren't any errors or deprecations. The PHPStorm log says:
IllegalArgumentException: Argument for @NotNull parameter 'psiElement' of fr/adrienbrault/idea/symfony2plugin/form/util/FormUtil.getFormTypeClassOnParameter must not be null
