I've verified that this bug happens for me as well when not logged in, but is not encountered after logging in. Looking at the Metacat code, it appears that the sessionData object below is null before logging in.
} else {
SessionData sessionData = RequestUtil.getSessionData(request);843 ---> userName = sessionData.getUserName();
password = sessionData.getPassword();
groupNames = sessionData.getGroupNames();
sessionId = sessionData.getId();
logMetacat.info("The user is : " + userName);

i'll check with Mike and see what's going on in this case. He's actively been developing in the area of sessions/users etc...
