With MediaWiki 1.11.0 on PHP 5.2.4 the page Special:Imagelist is completely blank - both on an upgraded Wiki as well as a new install.
I remember having found a forum entry a few weeks ago that claimed a PHP issue was responsible for this and therefore postponed the Wiki upgrade until a PHP upgrade would hit my Gentoo box. However, the error remains.
If you need more debugging info, I'd be glad to help you out with this.
Have you looked at your error_log, turned on error reporting in PHP and/or set $wgShowExceptionDetails to true? That might help to find the error.
It's no MediaWiki but a Gentoo package issue, the filerepo include dir was missing.
