I tried 2.6 as well.  Check the source of the returned page. 
I think you will find this:

<html>
<head>
<title>Workspace.2003-12-17.8140751750</title>
</head>
<body>
gerry.2003-12-17.8140751750
</body>
</html>

It seems to happen with any tuple... I tried this script:

return ('foo', 'bar')

... and got this:

<html>
<head>
<title>foo</title>
</head>
<body>
bar
</body>
</html>

Returning a list instead of a tuple is OK - it shows a string
representation of the list.

I would guess that you are right, this is odd publisher behavior.
File a collector issue.
