New JSF project kickstart libraries problems with Tomcat 6

When I created a new JSF project using Tomcat 6 and the kickstart with libraries option, the Tomcat server would fail during startup with:
18.12.2007 11:28:38 org.apache.catalina.core.StandardContext listenerStart

Manually removing the el-api.jar from WEB-INF/lib solved this issue.

When I tried using the kickstart template without libraries, Tomcat would fail during startup with this exception (complete log):
