I also needed to fix some other stuff on a file called gui.ty
self.title = unicodedata.normalize('NFKD',
the above line of code returned an empty string on my machine Win7 (line 89).
When 'self.title' is empty the service script gets no title to work with, thus I had to make some changes in the gui.ty.
If this is not the right forum to discuss this, please direct me to the right place.
let me know how to submit this fix
