I don't get those errors at all. Are you on Gtk.jl master?
To get what you expect for the case where you execute it from the command
line, you need to add
if !isinteractive()
wait(Condition())
end
at the end of example_gtk_function.jl. By making it conditional on
isinteractive(), it won't break the other two cases.
