Due to current rendering issues with tables / if statements etc, needed to enable $UseTidy. When this is done, the image table generated by the <gallery></gallery> tag gets messed up. It is also a problem with the RandomImages extension (suspect they use the same code somewhere). What appears to be happening is that some of the opening and closing tags of the code is generated as & gt; or & lt;. Which then means that things fail, get funny bits of code appearing on the page etc. The gallery generating code was working fine before enabling $wgUseTidy. Because of the tags being messed up, the following is visible under the thumbnails generated by the gallery tag (as well as with RandomImage): "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> More details of it are documented here - http://www.mediawiki.org/wiki/Manual_talk:%24wgUseTidy Problem since noticed it with 1.8.2.

It looks like you're missing the tidy configuration file. The default one we provide is in the extensions module, in extensions/tidy.
Sorry if this is a stupid question, but I have been searching high and low (Google, MediaWiki, MetaWiki) for a default tidy configuration file in the extensions module, and have found nothing. Not even really a mention of one. Where is this meant to be obtained from? FYI, Tidy is working, and it is using the configuration file that is the default for Tidy on the server itself. The configuration file exists, it is in the default location that tidy looks for the configuration file etc. Ahh, think I have finally found it: http://meta.wikimedia.org/wiki/Data_dumps#Common_Problems_and_Solutions under the heading "After I run importDump.php or mwdumper, the articles are messed up. Templates are skewed and do not display properly. what can I do?" Seeing if that is appropriate and fixes the issue.
That appears to be it! Damit, something so simple. I have updated the various locations where i have made comments about this, that a tidy.conf needs to be included. Will update some details in the manual about tidy to note that as well.
Note that I've moved the default location for the tidy.conf into includes/tidy.conf, so as of MediaWiki 1.10 it won't be necessary to fetch extensions files separately for this.
