(defmacro RunQt [args & body]
`(do ; <= here is the error
(try
(QApplication/initialize (into-array [~args]))
(catch RuntimeException e# (println e#)))
~...@body
(QApplication/exec)))

thus it tries to call the return value of the try form (which is nil)
only once all args are computed (ie when you close the window).
