Hello,
I have (had) an issue with Reports.get_report_list()

If I call get_report_list(max_count=100), I run into the error

File "/home/amzteu/app/bin/mws.py", line 85, in calc_request_description
encoded_value = quote(params[key], safe='-_.~')
File "/usr/lib64/python2.7/urllib.py", line 1280, in quote
if not s.rstrip(safe):
AttributeError: 'int' object has no attribute 'rstrip'

After some debug, this can be easily fixed by calling
get_report_list(max_count='100')
Basically passing a text instead of an integer (line 438, param max_count)

In my opinion max_count makes more sense as a number, so it would be better to edit line 444 into MaxCount=str(max_count))

Thanks,
Alberto
