i could not start playback - playlist was empty

Thank you for taking the time to report this bug and helping to make Ubuntu better. Unfortunately, we can't fix it because your description didn't include enough information. You may find it helpful to read "How to report bugs effectively" http://www.chiark.greenend.org.uk/~sgtatham/bugs.html. We'd be grateful if you would then provide a more complete description of the problem.
We have instructions on debugging some types of problems at http://wiki.ubuntu.com/DebuggingProcedures.
At a minimum, we need:
1. the specific steps or actions you took that caused you to encounter the problem,
2. the behavior you expected, and
3. the behavior you actually encountered (in as much detail as possible).
Thanks!

1. just open it and double click a radio station
2. i expected to play the radio station as it should
3. it just show me the error you already saw in the screen shot

Thank you for your bug report. The issue is an upstream one and it would be nice if somebody having it could send the bug the to the people writting the software (https://wiki.ubuntu.com/Bugs/Upstream/GNOME)

same here, confirming.

I've sent this upstream at: http://bugzilla.gnome.org/show_bug.cgi?id=591839

We are sorry that we do not always have the capacity to review all reported bugs in a timely manner.

The upstream bug has moved to
https://gitlab.gnome.org/GNOME/rhythmbox/issues/784
but has seen no activity in recent years.

If this is still an issue using a maintained version of Ubuntu then please let us know otherwise this report can be left to expire in approximately 60 days time.
