Stylesheet of regular backend_layout overridden
On editing backend_layout (the Core's backend_layout), editing icons are not shown in the wizard view anymore.
The reason is, that http://ip61.local/typo3conf/ext/gridelements/Resources/Public/Backend/Css//grideditor.css?1372058711 is used as CSS file instead of the Core's version of the stylesheet. I guess gridelements somehow overrides that stylesheet assignment.
