Dear Maintainer,
*** Please consider answering these questions, where appropriate ***

   * What led up to the situation?

upgrading 3:2.13.1-2 to 3:2.14.1-1 caused problems with some 3000*4000 jpegs
in vertical orientation semi-randomly silently failing to display.

3000*4000 jpegs also were not well interpolated for display to fit a
1920*1080 monitor.

Running under gdb failed to reveal anything. Surely a failure to display
an image should generate some errors visible somewhere?

   * What exactly did you do (or not do) that was effective (or
     ineffective)?

Downgrading to 3:2.13.1-2 fixed the problems.

   * What was the outcome of this action?
   * What outcome did you expect instead?
