What were you doing to at this time? scrobbling forward? Repeating one track or repeating a playlist?

What version of rhythmbox are you using and what distro?

[witmak38]

Sometimes when flipping through tracks, this happens or by itself over time. operating system: Elementory OS

[witmak38]

rhythmbox 3.4.4

[fossfreedom]

probably needs a bit of defensive coding around line 422 alternative-toolbar.py to escape from any errors rather than probably looping or whatever is causing the freeze.

could you please tell me how to do it. I am not familiar with python
