2) Hear a podcast and put Rhythmbox into the background
3) When the podcast finishes, click on the app-indicator to put Rhythmbox in the foreground.

What happens actually? Rhythmbox crashes.

I didn't have debugging symbols, I have downloaded them and will try to reproduce and generate a useful stacktrace.

This is a bug in rhythmbox-plugin-radio-browser. If this pluing is disabled I cannot reproduce it. I have reported the bug in the issue tracker for this plugin:
https://github.com/fossfreedom/radio-browser/issues/18

[rithik g (gkrithi)]

crash is in external plugin.

nothing to do with rhythmbox code. resolving as invalid.
