Title:
  Banshee hangs with YouTube context pane if the server 404s

Status in “banshee” package in Ubuntu:
  New

Bug description:
  I have noticed that Banshee has been hanging for me recently where it
  will seemingly randomly hang (the interface fades to grey) and I need
  to kill it to get it back. To see what was wrong I ran it with the
  --debug switch from a terminal and when it hung I got the following
  output (apologies there is not a full log, this was how much I could
  grab from the terminal scrollback):
