[Duplicity-talk] AssertionError on Uppercase path name

[Bill Bixby]

A new user of Duplicity.
Using Duply to drive it to backup a series of photo sub directories to Google 
Drive.

The problem I've encountered is that if the directory name contains uppercase 
I get this Duplicity AssertionError in path.py:
Traceback (most recent call last):
  File "/usr/bin/duplicity", line 1532, in <module>

and so on for a successful backup.

For my series of over 50 folders, every one that is all lower case works, 
every one that has uppercase in the name fails.
