Refresh stream broken

[trekiteasy]

The button to get another stream for a track seems to be broken in current dev version. When I click on refresh, I get the following error :

queue.js:56 Uncaught (in promise) TypeError: Cannot read property 'source' of null
    at queue.js:56
    at arrayMap (lodash.js:639)
    at Function.map (lodash.js:9554)
