Mapillary plugin crashes

[anonymous]

Since updating to the latest version of JOSM (and checking no plugins needed updating), the Mapillary plugin crashes when I try adding it's imagery layer. Initially this seemed to be the area was too big (would be better if it told you that nicely), but on a small error it seems to be getting a 500 error from the server.

Fixed, it was caused because of opening the layer without having a OSMDataLayer opened.
