I have enabled Subversion plugin in plugin manager, but left Emma and Msn plugin disabled. When I try to create Subversion Repository in configuration I get following error:

WicketMessage: Method onFormSubmitted of interface org.apache.wicket.markup.html.form.IFormSubmitListener targeted at component [MarkupContainer [Component id = form, page = com.pmease.quickbuild.web.page.configuration.repository.ConfigurationRepositories, path = 55:repositoryTypeMenu:form.Menu$1, isVisible = true, isVersioned = true]] threw an exception

Root cause:
