CSS and JS fail to load

[RowanKaag]

For some reason, in default.hbs, there are the following lines:

{{! Styles'n'Scripts }}
<link rel="stylesheet" type="text/css" href="{{asset "css/peeves.css"}}" />
... ... ...
<script src="{{asset "js/peeves.js"}}"></script>

Which are supposed to be perfectly fine, AFAIK. However, when applying this theme, neither gets loaded. When opening Safari's webinfo panel, the following error messages occur:

[Error] Failed to load resource: the server responded with a status of 404 (Not Found) http://********/assets/css/peeves.css?v=16ec85cf1d
[Error] Failed to load resource: the server responded with a status of 404 (Not Found) http://********/assets/js/peeves.js?v=16ec85cf1d

so for some reason, ?v=16ec85cf1d is added to the URL. Is this a bug?

Theme: 2.2.0
Ghost: 0.6.3
