I have spent quite some time confirming this after I first noticed it, including checking any related configurable parameters that seemed relevant, and I am reasonably satisfied that it is indeed a bug.
I have installed a new nightly - as of two days ago - installation of 1.5 to evaluate and test, using the sample data supplied.
I created a "Category List Layout" - which I assume is the same as a "Content Table Category" in the current Joomla - to list "Latest News" for which there is 11 articles.
The listing is displaying only "Date", "Author" and "Hits" but not the associated clickable page title so basically there is nothing to click to go to the article that should be listed.
This is the URL of the home page pf the site: http://www.mindpowercorporation.com/joomla15/
you can go to the listing my clicking "Category Listing" on the menu called "Top Menu".
The direct URL to the listing is: http://www.mindpowercorporation.com/joomla15/categories.html
I assume that this must be a bug - I cannot envisage there being an obscure option to display a category listing without the actual categories.
