Comment 1 for bug 336740

This appears to have been caused by the fix for bug 225876 (as attached). When the back button is pressed from the "Where are you?" page and on_steps_switch_page is called, the "step ? of ?" text is not updated because the code assumes it will be done when the UI is translated when the selection in the language list is changed, but since the user is pressing back, this doesn't immediately happen. This is evidenced by selecting a language from the list, which updates the text to the correct page number.
