    This was caused by a race condition when adding application &#243;&#212;&#233;&#188;
    module meta data into the server &#243;&#212;&#233;&#188;&#212;&#228;&#243;s list and occasionally
    causing the list to be corrupted.  The exception could happen
    when the corrupted list was subsequently accessed.
