Wrong direction arrows shows

I don't know if this is related to #178, but sometimes the wrong direction arrows are shows.

Take image http://mapillary.com/map/im/6t21NZGkTvytg3eLadNlBw. This image is directed roughly south, though the sequence is going east (photo made out of the right-side window). There are two rotation arrows shown: one to the left and one reverse (180 deg).

The arrow to left links to an image that is directed north, i.e. that should have been a reverse arrow, while the reverse arrow is linked to an image directed west, i.e. the arrow should have pointed right.

You see that same in surrounding images, http://mapillary.com/map/im/Z38rNJUc57XyUnrHVEKJpA points north and has an arrow to rotate right, linked to the previous image that is pointed south. And http://mapillary.com/map/im/hpbhcItVtDHnApOM6s-g9A (pointing west) has a reverse arrow linked to the previous image.

It's as if the sequence direction is used for the sequence, instead of the provided image direction.

(Note, http://mapillary.com/map/im/nSbSegvDkWoCVhTcG4S4dA which is directly next to a photo from the previous sequence, is not showing any links to that sequence at all.)
