Something similar happens if I try changing the title of the window, or in the :window_state_event callback. It doesn't happen in the :key_press_event, or :focus.

This happened on Windows 8.1, using julia 0.4.1. It worked fine on Ubuntu (virtual machine).

This works:

c = Condition()
w = @Window
@spawn while true
    wait(c)
    sleep(0.1) # removing this causes crashing
    visible(w, false)
end
signal_connect(w, :delete_event) do widget, event
    notify(c)
    true
end

Ah okay, I suspect they were related but wasn't 100% sure. Thanks for your attention, and best of luck.
