Hi ,

Today I opened for the first time my /var/logs/volumio.log to discover whenever a new song is pushed to the queue, several TypeError messages are logged.

No idea what this means, because I cannot relate to a visual glitch, but this doens’t look ok

Yes, this is an harmless error. It has however been fixed in a new version which will be released shortly.
