I've started to work with quickly and python (because I wanted to have some GTk3 integration and create and appindicator), and so I create the projecto like this :

quickly create ubuntu-application ualarm
cd ualarm
quickly run

And the application launched. But then I tried to add the appindicator like this :

quickly add indicator

And since then the application doesn't start anymore and this error appear :

aliasbody@BodyUbuntu-PC:~/Projectos/ualarm$ quickly run

self.indicator = AppIndicator3.Indicator('ualarm', '',      AppIndicator3.IndicatorCategory.APPLICATION_STATUS)
TypeError: GObject.__init__() takes exactly 0 arguments (3 given)

How can I solve this problem ?
