Color gradient with identical start and stop, transparency gradient

Open attached document. It contains an ellipse with a color gradient with
identical color on start and stop, but different transparency.

If you set anti-aliasing off, the ellipse is rendered full transparent. If you
switch anti-aliasing on, the ellipse shows the transparency gradient correctly.
Show mode is always correct.

Tested with Version: 7.1.0.0.alpha0+ (x64)
