Re: [Duplicity-talk] strange error when doing a backup

[Scott Hannahs]

Actually I am still getting a different error in the same module.  This is:
Mac OS X 10.11.6.
Python 2.7
duplicity 0.7.10

I back up several directories as independent jobs, and this only happens for 
one directory.  Of course it is the most important one!  And largest.  This 
does not seem to be an issue with encoding and gpg but still fails at the same 
line.  It looks like there is some access problem with the .cache files but I 
have r/w access to the directories and all files.
