Comment 10 for bug 699992

gtk_message_dialog_new should take the browser as the parent window.

1) Yes, at least say "Download failed". Not sure if we can get the error message easily, but we don't want users waiting "why is nothing happening there".
2) I'm used to seeing parantheses, but I agree they can be inconvenient. I don't know if there's a convention in use with underscore or dash, I am fine with either.
