Empty pie chart can show up as quarter circle

JS Fiddle: http://jsfiddle.net/Htwkm/
Browsers tested: Recent Chrome and Firefox

The behavior of empty pie charts with dataLabels off and animation off has changed between 3.0.2 and 3.0.4. This pie chart should show up totally empty (which it did under 3.0.2), but in 3.0.4 it renders as a quarter circle.

If you set animation to "true", it renders correctly.

Bonus bug: If you turn dataLabels to on, it will freeze the browser (best done in Firefox, which recognizes the JS engine is stuck and allows you to cancel it). Firefox gives this message:

A script on this page may be busy, or it may have stopped responding. You can stop the script now, or you can continue to see if the script will complete.
