Example file demonstrating the problem

WebKit's implementation of linear-gradient doesn't support combinations of start position and angle parameters as specified by the draft: http://dev.w3.org/csswg/css3-images/#linear-gradients
Example attached, along with screenshots from Firefox 4.0b9 and WebKit Nightly r76498.

We are compliant with the current spec. The syntax for linear-gradient is:
<linear-gradient> = linear-gradient(
[ 
	[ [top | bottom] || [left | right] ] 
	| 
	<angle>
,]? 
<color-stop>[, <color-stop>]+
);

so you provide either a start point, or an angle, but not both.
