Warning when updating to version 0.3.10

[Oliver Klee]

I have updated to usb-creator-kde using aptitude. During the update, this warning is displayed:

/usr/lib/python3/dist-packages/usbcreator/frontends/kde/frontend.py:140: SyntaxWarning: "is not" with a literal. Did you mean "!="?
  if self.__img is not '':

(I don't know whether this problem also occurred with earlier versions, i.e., whether is it a regression. I also don't know whether this problem only affects the update or also the installation.)
