Title: Fix crash when switching to the Artists view

It's crashing here when I'm switching to the Artists view. It's throwing a TypeError when printing a tracker.get_url() return. When tracker.get_url() returns NoneType, you can concatenate it to a 'str'.
Apparently, logging.debug handles that.

btw, sorry for the long-name-branch. :)
