IE8 Error in jQuery.extend()

[gzoller]

Invalid argument. (jquery-nightly.js, 5938) in IE8 (haven't tested other IE versions)

Currently from nightly 3/12/10:

5938: fx.elem.style[ fx.prop ] = (fx.prop === "width"

fx.prop === "height" ? Math.max(0, fx.now) : fx.now) + fx.unit;

Possible Fix:

5938: var value = fx.prop === "width"

fx.prop === "height" ? Math.max(0, fx.now) : fx.now;

5939: fx.elem.style[ fx.prop ] = (isNaN(value) ? 0 : value) + fx.unit;

It doesn't look like this is related to .extend() - can you provide some code that triggers this error?
