I am reposting my question since we upgraded media wiki to 1.4.7 and
are still experiencing the same behavior.
The internal wiki links in MediaWiki are either blue (click to view an
existing article) or red (click to edit a new article). This coloring
applies to the tabs at the top as well.
We have a number of stub articles in our wiki that are showing their
discussion tabs as red, even though the discussion does in fact exist.
It is only happening on the articles tab (discussion is red in color
when it is not new) but it doesn't happen for any other tabs.
Here's an example:

Thank you.
