    <p>Hi Strahil,</p>
    <p>I poked around our logs, and found this on the front-end (from
      the day & time of the last time we had the issue)</p>

    <p>This would indicate that the problem is related.  For us,
      however, I believe we can reproduce this issue at will (i.e.
      simply try to gunzip the same file). Unfortunately I have to go to
      a meeting now, but if you have some specific tests you'd like me
      to try, I can try them when I get back.</p>
