Well, according to the documentation that method needs to return a string: 

	onDownloadStart: function(){
		// summary:
		//		Called before download starts.
		// description:
		//		The string returned by this function will be the html
		//		that tells the user we are loading something.
		//		Override with your own function if you want to change text.
		// tags:
		//		extension
		return this.loadingMessage;
	},

So, please update your test case to do that and let us know if there's still a problem.

Alternately, maybe you want to connect to that method instead of overriding it: 

<div data-dojo-type="dijit.layout.TabContainer">
   <script type="dojo/connect" data-dojo-event="onDownloadStart">
      console.log("hi");
   </script>

Your language is fine but there's a problem with your code. You still aren't returning a value. You are effectively doing: 

onDownloadStart = function(){
    myFunc('action');
}

Hopefully you can see that the anonymous outer function isn't returning any value, regardless of what myFunc does.

You could just say in the markup: 

onDownloadStart="return 'hi';"

to make it work.

i will not insist on my opinion,but can you test my first example with dojo 1.5.2?

OK, I tried on 1.5, and it works there, but still, it was always specified that you needed to return a string from that onDownloadStart method.
