failed to load null resource when contentsCss set to null in webkit

[David Wipperfurth]

Low Priority

In webkit browsers if contentsCss is set to null, an error is thrown about failing to load a resource with a URL of ​http://mydomain.com/mypath/null

I'm guessing this occurs for all browsers but webkit is the only one that complains about it.

To be clear I'm not setting contentsCss to 'null', I'm setting it to null. e.g.

jQuery('textarea').ckeditor(function(){something=this}, {

resize_enabled: false, skin: 'jqui1', contentsCss: null

});

config.contentsCss is supposed to be a none-empty value, it's depends on your application to provide be defensive over null value.
