    this BUG() means that a dquot structure was removed
    which, at this moment was not on the free list of quotas
    (where it should have been for removal) ...

    further this resulted in a bad access ...

    this is a problem, which is probably fixed in
    later versions of the quota code, but YMMV ...

    HTH,
