"basePath" is relative to "C:\" instead of config file

I'm running into an issue when trying to run karma. I am running it via gulp task and when it runs it logs Executed 0 of 0 ERROR. In the log before that I found this:

WARN [watcher]: Pattern "C:/bower_components/**/*.js" does not match any file.
WARN [watcher]: Pattern "C:/src/**/*.js" does not match any file.
WARN [watcher]: Pattern "C:/tests/**/*Spec.js" does not match any file.

All these files should be relative to the location of the config file(as described in the documentation), not C:\.

Here is my gulp task:

var karma = require('karma').server;
gulp.task('test', function (done) {
    karma.start({configFile: '../../../karma.conf.js', singleRun: true}, done);
});

Related config parameters:

module.exports = function (config) {
    config.set({

...

        basePath: '',
        files: [
            {patterns:'bower_components/**/*.js'},
            {patterns:'src/*.js'},
            {patterns:'tests/**/*Spec.js'}
        ],
        exclude: [],

...

    });
};

This is my first attempt at adding Karma to my workflow, so I hope I'm not missing something obvious.
