Searching a mail archive breaks with the following exception:

org.apache.velocity.exception.MethodInvocationException: Invocation of method 'getExcludedMailCount' in class com.atlassian.confluence.pages.actions.SearchViewListPagesAction threw exception class java.lang.NullPointerException : null

Furthermore the mails are not ordered by date. This makes finding a mail a tough job. It would be nice if someone could fix this asap.
