Description of problem: If you use the GUI anaconda as you ask for an upgrade (click the radio button/hit Alt-U), if you've done askmethod and given an HTTP URL, you get a traceback due to "if self.togglecb is None:" where togglecb isn't an attribute of self (gtk radio button widget). How reproducible: Always. Additional info: Text mode works.
