I just bought a new Model A+ board, and noticed that the GPIO pins 13 and 14 (board pins 21 and 23) are soldered together on the backside. This was not the case with my previous A+ board: see the two compared side-by-side below.

  1. Is this an error in the board, or the intended configuration?
  2. If this is an error, should I remove the solder before using the board (even if I don't intend to use these pins)?

New vs old board

No they should not be soldered together (this is called a solder bridge). You should initiate a return request. You could cut or rework the trace yourself, but I would still suggest returning it - if you have problems down the road you may not be able to successfully return it if you cut the bridge yourself..

    If you have a good iron, I'd ask support if I can attempt to rework it as that error could literally be solved in seconds with 3 cents-worth of braid rather than the huge hassle and cost of RMA'ing the thing.

    My iron doesn't get hot enough to do the job, so I got in touch with Newark about replacing the Pi. Thank you both for quick replies!

They shouldn't be soldered together, try returning it and DO NOT use it during the time as something could happen.
