Thread:Project:Support desk/Thumbnail error: "command not found"

When trying to render SVG thumbnails using imagemagick I get the following error, every time, no matter what I try:

MediaWiki version: 1.17.0

PHP: 5.2.6RC4-pl0-gentoo (apache2handler)

MySQL: 5.0.54-log

Any idea what might be causing it? It's been frustrating me. 81.141.71.93 13:35, 26 August 2011 (UTC)
