Threw me completely, so I missed the obvious - setting the .tld file in web.xml removed the problem: <taglib-location>/WEB-INF/mmbase-taglib.tld</taglib-location>
Are you suign the 1.7 release? Because in that release you set the tld by pointing to the mmbase-taglib.jar:
<taglib-location>/WEB-INF/lib/mmbase-taglib.jar</taglib-location>
