I tried commenting line 39, and ran the sample. it works. Is commenting line 39 
the right way to debug the code?

list_next() will return None if there are no more pages of results. I will make 
the code more robust to that possibility.

I have checked in a fix to the sample that checks for None before calling 
list_next().
