Well, gnus-group-real-name worked here using the group that you
provided.  The debug message also looks rather bizarre so let's assume
that the problem is in the byte-compiled file.  Try deleting, or at
least renaming, the gnus-util.elc file so that the gnus-util.el file
will be loaded.  That should either give you a better error message or
fix the problem.  If it is the later, you'll want to recompile
gnus-util.el.
