    Hi Felix,
    
    I think this issue was introduced by [1] in 5.3 and fixed by [2] in
    5.4.   Looks like Jeff didn't realise he was fixing a regression and
    didn't flag the fix for backporting.
    
    There is nothing we can do about 5.3 now, so upgrading to 5.4 or 5.5
    is probably the only option.

    Thanks,
