That got me started, I had to disable devel so it found an older version of Google Voice...

However, I got a different error this time (more complicated):

From line 560 in the gui module in set_chapter

self.chapter_button.set_text("Chapter", chapterIndex)
TyoeErrorHildonbutton.det_tect() argument 2 must be string, not int

Hope that helps,
Fred
