MapRoulette plugin fails to download tasks.

[soaks_jinxes.5q@…]

Hello all!
Here's a problem I've had on Mac on the latest version of JOSM with the MapRoulette plugin.
Thanks in advance!

What steps will reproduce the problem?

1. Attempt to download MapRoulette Data either from the Download Data window or use the "Edit in JOSM" button the MapRoulette.org website and then click on the plugin side bar the button that says Download Map Roulette Tasks
2. Click on the update (or keep) button of the popup that asks whether you want to update the MapRoulette plugin.

What is the expected result?

The plugin downloads all of the MapRoulette tasks in the area.

What happens instead?

I get a popup that "An unexpected error occurred..."

Please provide any additional information below. Attach a screenshot if possible.
