Please describe the problem:
I was going out for the evening and I decided to leave Rhythmbox playing the
songs from my music library with shuffle and repeat turned on (because I leave
in a country where people do such things in combination with keeping the lights
on in hope of driving some robbers away). I minimized the application windows to
the notification area before leaving. So when I came home after 6 hours, I
didn't head the songs playing though I'd chosen the repeat option and I clicked
on the icon in the notification area but the main window didn't appear. I tried
right-clicking on the icon to get the context menu but it wouldn't pop up.

So I instructed GDB to attach to the rhythmbox process and obtained the output
of 'info thread' followed by 'thread apply all bt'.

Because the output that I got is approximately 64K and the comment entry doesn't
allow me to sumbit the output inside of it, I'll try to give a shorted summary
of it:
