missing gap between icons and text in reports using standard theme (SOLUTION INCLUDED)

using standard theme
and accessing the "Activity report"
there is no gap between icons and text displayed on the right.

See attachment for more details.

A way to fix this, is by changing line 80 of theme/base/style/core.css
from

img.icon {height:16px;vertical-align:middle;width:16px;}

to

img.icon {height:16px;vertical-align:middle;width:16px;padding-right:4px;}
