Some image URLs are not preserved in re-exported theme

[lxg]

When I import a theme, modify it and download it again, some of my modified image URLs (images/… → /img/jquery/…) are preserved, which is a nice feature. Unfortunately, some of them (e.g. the path to the AJAX loader) are reset to the jQM default.

Here's an example:

$ grep -e 'images/' -e '/img/jquery' my.exported.theme.css
        background-image: url(/img/jquery/icons-18-white.png) /*{global-icon-set}*/;
        background-image: url(images/icons-18-black.png);
                background-image: url(/img/jquery/icons-36-white.png) /*{global-large-icon-set}*/;
                background-image: url(images/icons-36-black.png);
        background: url(images/ajax-loader.gif);
