Often when I run Duplicity I see an error message like this at the end of the run:
Cleanup of temporary file /home/user/.cache/duplicity/9a169830d41477b2dbc3c5b32edd4e8a/duplicity-MEXhMY-tempdir/mktemp-StAkzj-1 failed
The mentioned directory will contain ten or so files that are deleted the next time I run Duplicity.
Any idea why this sometimes fails when running incremental backups? I have not seen any pattern to it myself, and have had little luck in finding others mentioning the same issue. Some guy on some emailing list once mentioned that his locale caused problems for Duplicity. I tried changing from my normal Norwegian bokmål locale to en-US, but still see the issue.
Is this just normal operation for Duplicity?
Seeing it on three different systems: two Ubuntu 13.04 64-bit desktops and one Ubuntu Server 13.04 64-bit.
