We bundle flora.css, flora.tabs.css, flora.tablesorter.css in a couple of different places. (grep the code) If you include report_list.less into this we can't reuse the same bundle in other places. 
Basically, I suggest you do just 
```
{% compress css %}
<link media="screen" href="{{ static('crashstats/css/report_list.less') }}" type="text/less" rel="stylesheet" />
{% endcompress %}
{% compress css %}
....
```
