Volunteer has given me more details on the error below.  He says "I had
Mint 17.1 running on the laptop and on the box we have IIAB on...these
errors are from the laptop.  We are using Firefox for the web browser...I
added Flask after the fact to the client but I had Flask running on the
IIAB box.  I will be happy to look closer if you need anything."  (And
apologies this is not explicitly an XSCE question, but they may use that in
future.)
