Nightwatch: .getLog('browser') in Firefox doesn't return (possibly empty) array of log entries

[stayen]

OS: Ubuntu 16.04.2 64-bit
Nodejs: 4.2.6
Nightwatch version: 0.9.15
Geckodriver version: 0.17.0
Selenium version: 3.4.0

Minimal test code:

client.getLog('browser', function(logEntriesArray) {
    console.log("Log object %o", logEntriesArray);
});

Expected output: array of log entries, probably empty (array of objects with properties 'message', 'level', 'timestamp').

Actually received output: something like below:

Test settings for FF are taken from Nightwatch.js configuration sample:

"desiredCapabilities": {
    "browserName": "firefox",
    "marionette": true
}

Is there any headway on this? I've been able to reproduce this.
