The "coordinates selection interface" is the one with the page image and the green squares. The production site sporadically 500s at this point, while dev versions occasionally don't display the boxes until the "All" button is clicked.
I have yet to replicate this, but all 500 errors are being logged properly as of today, so it should be straightforward enough to track it down and fix it if it happens again.
