@clovis86: can you check if the old version works? If not you'll probably need to delete /home/nemo/.local/share/harbour-cutespotify (This bug happens only very seldom and is thus hard to debug).

Or even better first run the app from terminal:
harbour-cutespotify --debug 2> log.txt and send me the log.txt file.

@junnuvi: On which device do you test? What doesn't look good?
