Application Errors on Startup "TypeError: Can't convert 'NoneType' object to str implicitly"

So.. this might be because I don't have a device that's supported by the daemon yet (I have the Diamondback Chroma).. but I thought I'd report this error that happens on launch of the polychromatic-controller:

cornelia@Xaos-OryxP:~$ polychromatic-controller       
Using relative path for translations.
Traceback (most recent call last):
  File "/usr/bin/polychromatic-controller", line 125, in load_changed_cb
    app.page_loaded()
  File "/usr/bin/polychromatic-controller", line 445, in page_loaded
    self.refresh_device_list()
  File "/usr/bin/polychromatic-controller", line 1393, in refresh_device_list
    app.update_page('#' + selected_ui, "addClass", "active")
TypeError: Can't convert 'NoneType' object to str implicitly

I figure, even if the user doesn't have any daemon supported devices the application probably shouldn't error like this.. If anything, it should notify the user of missing devices, etc.

Thanks for reporting. Indeed, there should be a "No devices found" screen, but some logic bugs were in the way. It's now fixed in the latest master. 👍
