Error can't find module when using less-loader and "module" options

[zxcabs]

Hello, when i use "background: url(./icon.png)" in my less file i got error Module not found: Error: Cannot resolve module 'icon.png'.

Here part of webpack.config.js file

module: {
            loaders: [
                {
                    test: /\.less$/,
                    loader: ExtractTextPlugin.extract('style', 'css?module&localIdentName=[hash:base64:5]!postcss!less')
                },
                {
                    test: /\.(jpg|png)$/,
                    loader: 'url-loader?limit=100000'
                },
                {
                    test: /\.svg$/,
                    loader: 'url-loader?limit=10000&mimetype=image/svg+xml'
                }
            ]
},

If remove module options or less-loader all works well.
