function bound to ready event fires twice on 1.4.3

I'm currently using Firefox 3.6.10 and Opera 10.60 on Slackware Linux 12.1.

In jQuery 1.4.2, a function bound to the document ready event fires once. The same is not true in 1.4.3. A simple test case can be found at:

For the test case above, the jquery version number should appear only once. It shows up twice for 1.4.3.
